PSR-800 Scanner not recognized

[JlMMY]

I had this problem, when I first installed the EZ Scan software, from the included CD. The driver from the CD is the correct driver. As pointed to above the CD contains the .INF file. Windows 7 will not correctly identify the driver on the CD by default? I had to update the driver, using Device Manager. IDK about XP?

That's basically what I took the long way around to say

This just happened to me and it took me a few to figure it out. Happened on a specific PC with 2 different (one old version and one new version) PSR-800s. When I would plug either scanner in to the PC in question, in the Device manager, it would show up and an unknown device and "GRECOM PSR-8OO Scanner". Notice there are two OOs in the name and not two ZEROS. When plugging either scanner into a laptop, they would show up and "GRECOM PSR-800 Serial Device" and was recognized by the laptop. I went back the PC that wasn't working and did the below.

1. Open the Device Manager
2. Right Click on the unknown device "GRECOM PSR-8OO Scanner" and select "Update Driver Software"
3. Click on "Browse my computer for driver software"
4. Click on "Let me pick from a list of device drivers on my computer"
5. Under "manufacture" (on the left side of the window) find and select GRECOM
6. Under "model" (on the right side of the window) find and select GRECOM PSR-800 Serial Device
7. Click Next
8. Click Yes at the warning
9. Click Close
10. Scanner should now show up as a recognized device and have the COM port listed

I had a similar problem 2 days ago under Win 7 x64. Scanner hung while booting, and when attached to the computer via USB, it would not be recognized by the computer and displayed the small power cord icon in the upper right hand corner after displaying "Initializing uSD" (no clock display). I removed the MicroSD card and used a USB adapter, then optimized the SD card in EZScan software and problem solved.

will the software screw up if there is no scanner connected?

No but you may run into problems if you have more than 1 instance of EZScan running at the same time.

At first, the PC acted like it was seeing the scanner correctly, but it kind of didn't. Doing an update to the CPU, it saw it fine. Trying to do a DSP update, it didn't see it even though the PC showed it was OK. This is with two different PSR-800s.

That'll work if you are just updating the microSD card but not if you are updating the CPU and/or DSP.

Thank you for that

I forgot to mention that I was doing a DSP firmware update and it hung up on the computer after the download (installation progress bar stuck at zero) and I believe that's what caused the issue (scanner not booting and not recognized by the computer). The scanner would not boot and wasn't recognized by the computer until I optimized the SD card with an external card reader.

I'd strongly recommend using an external card reader to optimize the MicroSD card in EZScan to see if that will resolve the issue if the driver reinstallation doesn't work.

Had the problem of the laptop not finding the driver for the scanner. Using V1.08. Laptop is a HP i7 with Win 7 64bit. After trying all the above suggestions I was still getting device driver not found. I have 4 usb ports on this computer. 3 ports are USB3 and the other one is USB2. I had been connected to the USB3 port. USB3 is suppose to be backward compatible. I had my trackball in the usb2 port. After trying the other 3 ports (USB3) I unpluged the trackball from the usb2 port and connected the PSR800 cable. The computer loaded the driver and I was able to update and use EZ Scan. Moral of story is try all your USB ports. Also I connected to the 3 USB3 ports and it still does not recognize the scanner even after working on the USB2 port.

I have yet to get anything USB 2.0 to work in USB 3.0 ports ever since I first got a motherboard with 3.0. The backwards compatible claim is full of BS to me. I bought & installed a new Gigabyte MB last week and the 3.0 still wouldn't work.

I've had the exact opposite luck with the USB 3.0 ports on a fairly new ASUS motherboard.
Everything I've plugged into them worked fine including an old USB 1.1 speed thumb drive.

I even see far fewer occurences of card corruption or other issues with EZ-Scan communicating with my PSR-800 when I plug it into the 3.0 jacks.

I do usually use a card socket reader but sometimes I like to run the Check All utility for CPU and DSP updates so those must be done with the 800 connected.

The USB 3.0 ports are used under XP 32 bit and Win 7 64 bit on the same machine and they are Renesas Electronics chipsets and drivers.

With all that said, the PSR-800 seems to be picky about USB connections.
I have several short usb extension cables rated for at least 2.0 speeds.
They work fine for transferring gigabytes of data to a card or thumb drive but seem to cause the PSR-800 to see data corruption or when doing the Check for All Update from EZ-Scan, the 800 will do weird things like not power itself off when instructed by EZ-Scan to do such or it will totally corrupt the card. And this is with ports hooked directly to the motherboard and no internal cables like front ports would have. I rarely see those problems when I use the USB 3.0 ports.

I have two 1 foot usb extensions cables I use that seem to be the most reliable with the PSR800. The other cables work fine with everything else I have but not with the PSR800 for some reason that I've never figured out.
I think the PSR800 has some goofy USB interface chips in it that are flaky if you ask me. They run slow and appear to only run at usb 1.0 speeds even though you will get a warning if you plug the PSR800 into a USB 1.1 or 1.0 port telling you that it will run faster if hooked to a USB 2.0 port.
That tells me it does have a USB 2 chipset but the speeds are the same when doing a database update with the card in the scanner and plugged into a USB 1.x or 2.x or 3.x port. They all run really slow at usb 1.x speeds.
Something between the jack and the card slot is limiting the speeds to USB 1.x speeds in my opinion. I bet whatever is the cause is also the reason for so many to experience data corruption when doing updates with the card in the radio.

So it appears that Windows 8 Pro x64 will not allow unsigned drivers, and guess what? GRE drivers are unsigned. Going to have to install a VM with XP.

FTDI drivers here Virtual COM Port Drivers

[maus92]

Tried them. It will assign the scanner a comm port (7 in my case,) but the scanner still sticks on waiting for USB.

OK, so after a very frustrating hour, I figured this out, after buying my scanner (at least for my case), so I hope this helps someone at least.

Two things....

First, I HAD to plug the cable into a port on the motherboard, not a port on the front of the case.

Second, and this is odd....I had to hold the USB cable "mini" connector and GENTLY press away from the front of the scanner (so with the scanner is laying down face-up, I pushed the connector GENTLY downward). If I did NOT push the connector downward, the connection was intermittent as I discovered. After switching to a "hard port" on the back of the motherboard, I actually got it to connect. So my first mission was to upgrade the CPU and DSP (since you MUST connect to a computer to do that). Right in the beginning of the update process, the scanner hung on the screen that said "waiting for USB". Even after unplugging, and removing the batteries, the message was stuck on there, and I was understandably furious, so I started fiddling. I found that by pushing the cables connector towards the back of the scanner, the connection was fine, and I could do my updates, program, etc. Your arm might get tired waiting for a bunch of data to transfer and to optimize the scanner though, so I suggest doing what I did, and using your cellphone or some other reasonably light object to hold the cable in the correct position.

Obviously the connector in the scanner is not working as it should, but by now there is not choice but to deal with this issue as GRE no longer exists. At least I got my radio updated though, and putting data on the card can be done by putting the card in a card read and using a computer to transfer the information.

If this helps anyone, please let me know.

It seems to be safer to do the card updates in a card reader. I wish we could update the CPU & DSP through the card too.
