USB Not Recognized?

Hi,

I've been using the 6700 for the past 2 months or so with no problems but now all of a sudden, my computer won't recognize the USB device. I have been using PDAJ's WM 6.5 ROM since the beginning of the 2 months.

Here's what the screenshot says:

"USB Device Not Recognized

One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it. For assistance in solving this problem, click this message."

When I click it, it just takes me to a sort of device manager-looking screen but it doesn't really help.

I'm running WinXP.

Does anyone have any ideas/suggestions?

Thanks in advance

Have you tried to re install Active Sync ?

Yeah, try removing Active Sync and re-installing it.

Also, is there any irregular behavior on the AC charger? If the USB jack is coming loose, it will make poor connections with your charger and PC. If you think this may be the case, DO NOT WIGGLE THE USB CONNECTOR to test it. I learned the hard way. TWICE. It's much easier to repair a loose jack than to solder a new one on. It sucks. alot

the problem ended up being a loose usb port. i had to charge the phone by smashing down on the usb while it was plugged into the computer. luckily, i was able to do this for long enough (i held it the whole time) to flash my phone back to the oem and then take it to sprint to get repaired.

Hey there,

You might find this funny but from my experience I belive its a software thing or some kinda low level firmware related issues only after updating have I experienced this to Winmo6.5. I know it sounds strange but I have had this several times but only after flashing the unit . I put the unit into bootloader mode from serial to usb and the I see the connection when I connect the cable on the phone and the computer . It makes a connection but windows on the computer dont see it and the device some kinda of communication error of sort. So I researched this over and over and it only came down to updating the device has caused this. So with that being said as a last resort I opened the unit reflowed the Usb port. It worked in my situation. It was purely a last ditch effert and the usb connection was there(soldered) , it worked for me hope this helps .
