BCD436HP/BCD536HP: USB Mass Storage - PC not recognizing

[KR3LC]

Suddenly my main PC is not seeing the BCD436HP any longer. Neither in Sentinel nor as a mass storage device in Windows Explorer. Another scanner model and brand I have is readily recognized though.

Installed Sentinel on another PC and connected the same BCD436HP and Windows reported the USB device was not recognized and failed to connect. Turned off and on the scanner and connected and reconnected several times and got the same error over and over. Tried other cables too. No luck.

I had the USB connector replaced earlier this year out of warranty due to an intermittent connection. Maybe it has failed again.

Any suggestions? I could wait until Uniden calls for my scanner for the clock repair and then add this to the service request. In the meantime is there any other way to update the data and the firmware?

Thanks,
Rick - KR3LC

Replace the SD card.

You could also try reformatting it if you have a card reader, but if the card is going bad the replacement is the longer term solution.

Do the SD card thing. I remember having the same, or similar, problem and research showed that the SD card was the usual culprit. I reformatted the card and problem solved.

Of course, if you have anything on that card of any value, reformatting it will delete all of it.

But, then again, you can't read it anyway under the present circumstances.

You can, of course, replace the card, too.

I'd be tempted to try connecting a thumbdrive that is known to be working, to the PC and see if it is recognized. If not, my thoughts would be a bad USB port on the computer. (If you don't have a thumbdrive, any other USB port device would work for trial purposes such as a camera, iPhone, etc.)

If the port is recognized by another device, perhaps the connecor on the scanner has gone bad. I haven't seen any report of this happening, however.

If you have an SD card reader capability on your computer, you can remove the card and insert it into the card reader, bypassing the whole cable connection business.

Thanks for the replies. I have pretty much tried all those things before my first post but didn't think to give all the trial and error information.

1. I have a backup SD card that always has the same information on it as the card I use daily. Neither the backup or the regular card are seen when using the scanner in mass storage mode. The backup card can be accessed from the PCs card reader though the regular card cannot. The scanner works fine from either card except for mass storage mode.

2. I have tried a second device on both USB ports of the PC. No problem. One device I tried is a PSR-800 scanner. Another was my phone.

3. For the price I guess a new SD card is a cheap enough test but I feel like the scanner itself is the culprit. Though it is odd that both cards operate the scanner, neither can be read by the PC while in the scanner, and only one can be read by the PCs card reader.

Also make sure you're using the latest firmware, and you might want to try uninstalling the driver and letting Windows reinstall it. What OS are you using? Is there any indication the device was plugged in (device tone of PC)? If so, does it show in Devlce Manager? Is there an error indication there?

 

[KR3LC]

I don't know how to install the latest firmware if the scanner cannot be seen by the PC. I'm unaware of any drivers needing to be installed except in serial mode. I'm using Windows 7 Home Premium 64-bit. On my main PC there is no tone, nothing to indicate a connection has been made. I have tried two other machines too and they both simply indicate an error.and unable to recognize the USB device. I'm going to get a hold of a new card and give it a try.

Thanks for your responses and suggestions.

Rick

Did you try a different USB cable? Any USB cable with the mini usb will work to try it.

Sorry... I see you tried different cables...

Could be the jack on the scanner itself then... Maybe...

 

[ofd8001]

Greatest suspect: port on the scanner has gone bad. Least suspect: bad cable, especially if you've tried other cables.

True on the firmware...

The card uses drivers. The difference relative to other models is that the drivers are standard in Windows. That doesn't mean they can't get corrupted or updated to versions that don't work.

I think the card will fix it.

 

[KR3LC]

Thanks everyone for your suggestion. I have now tried a brand new Sandisk card. No go. In the card reader I was able to prepare it for new use, install data and update the scanner firmware too. The scanner works fine otherwise but I cannot get yet a third computer to see it. Windows reports a malfunction of the USB device.

So I deduce the scanner USB port to be malfunctioning. Seems the only conclusion to come to after trying several cables, several computers and 3 different cards, one of them brand new..

So when Uniden calls for my scanner for the clock campaign I will also report the USB problem. I hope they fix it for no charge because I paid to have the USB connector replaced earlier this year because of a physical break that made it intermittent. Different symptom this time though.

Is the card properly formatted (FAT32)?

Did you perform the CLEAR USER DATA on the card which writes the basic files?

Did you try removing the driver and letting Windows re-install it? I've seen cases where some have installed the Serial mode driver in the place of the Mass Storage driver. The solution is to do what I said two sentences ago.

You are selecting MASS STORAGE when you try to connect it, right?

 

[KR3LC]

Voyager, yes. I did all those things. The scanner, with a new, properly formatted card is working fine except that even on two virgin PCs, having tried a few cables, Windows says the USB device could not be recognized. I take the card out of the scanner and use a card reader and all is fine.

 

[Voyager]

Still sounds like a driver issue. The card reader might be using a different driver.

But, you said you tried removing the driver and letting it re-install, right?

If it was a driver issue the computer would still chime that it can see it. It just would not be able to access it. He said he is not hearing the windows sound to acknowledge that. That is not a driver issue.

Folks,

I appreciate the continued dialog. Though I have convinced myself of a defective scanner I will continue to follow further suggestions, at least until Uniden calls for my scanner for the clock repair.

I have uninstalled the driver after getting the Windows error message only to get the same message again and again.

The first message I get says this:

USB Device Not Recognized

One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it...

This leads me to another message that states:

Try reconnecting the device. If Windows still does not to recognize it, replace the device.

That pretty much is telling you something is wrong with the scanners usb port...

 

[Voyager]

Now that you said it is working with the card reader, try updating the firmware. Once you install it in the scanner, it should read the file and update, and that may just solve the issue.

Did you read thread 11....
He programmed his card in the reader firmware update and all... The scanner works fine... No go with usb port on scanner...

 

[Voyager]

Yes, I read it, but I did so when he posted it and I don't have an eidetic memory. I did remember post 7 where updating was an issue and he asked how he could update without seeing the old card. (to which I agreed in post 10)
