Weird USB problem

Postby ventsyv » Mon Jan 17, 2011 8:17 am

I'm seeing a weird USB problem. I connect to a device running Windows CE. The device is recognized, Windows sync starts, and I can browse the file structure on the device through Explorer. If I start copying a larger file though (1MB or so), the device stops responding and the connection is interrupted. Sometimes it works, but usually I have to try a few times before the file copies. It does seem to work fine for small file - around 100k or so. If I unplug the usb cable and plug it back in the connection resumes (but the file transfer has failed).


Sorry for the rant, just wondering what is going on...

Reminds me of a problem I had years ago with my PSP. If I recall correctly, it was an issue with it being plugged into a high speed port on the PC. Try connecting it to a low speed port (if you have one) or through a USB hub.

I switched the cable and now everything works fine. Very weird because I had no problems connecting and transferring smaller files ...

i think it's about USB2.0 and 1.0 issues. i guess, some older PCs have USB1.0 and newer gadgets that have USB cables for transfers has 2.0 installed in them. somehow, i can recall some time ago that i experienced that too, its just a compatibility issue. :thumbs:
