If you have another USB cable you might want to try it, some folks seemed to have gotten bad USB cables.Ok Running Win 7 and when I plug in the scanner in usb mode I hear the noise detecting - says installing software then errors saying no drivers found for this device.
USB woes on Win 7.
Have you tried to use the program that Uniden recommends to format your SD card?I'm having the same issue on multiple Windows 7 computers with both the 436 and 536. I've tried multiple USB cables. Sometimes reformatting the SD card works. Other times (like tonight) it does not. When connecting in mass-storage mode the drive is presented to the OS, but Windows insists it is not formatted. Though it works fine when I turn on the scanner.
Several people have reported this across multiple sites. Uniden needs to let us know what's going on. This isn't a cable issue. Either the mass storage support in the scanner is crap and/or buggy, or there's some updated driver we need that we don't have.
The one thing I have not tried (yet) is an external card reader to remove the scanner from the equation. I don't have one here, but I'll borrow one tomorrow and report back.
What firmware are you using?
The radios that I tried to connect were using the new 1.03.03 firmware.
Neither radio would connect directly but I kept the BCD536HP and just use a microSD card reader to access sentinel for firmware and database updates. I can't get the Scanner to set up the drive properly without the "Drive not Formatted error in windows".
Any chance Uniden will release a Mac OS X or IOS version of sentinel in the future. I can't stand using windows software.
