Hi, Have any of you had USB OTG Function (ActiveSync) working with Tiny210 or Mini210 on WinCE 6? I'm using the TinySDK board. It works correctly for me in WindowsXP but in Windows 7 I get the response “Unrecognized USB device” with PID=0,VID=0. (Note that I'm not talking about x86 vs 64 bit driver issues. The PID and VID recognition should happen before the driver loads, regardless of if your machine is 32 or 64 bit) But in WinXP this works OK and has correct PID and VID. Do you have any idea what could be wrong? Both are USB High Speed but also if I try with Full Speed I get same response. I've tried multiple Windows 7 machines which don't work. Have tried connecting board to my benchtop oscilloscope USB host port and that works. Tried different cables. It seems that the fail happens after the link speed is established as there is no Start packet. After several "Reset Again" events the connection is suspended. I put in the 6410 in the Subject line as the source code is basically the same so perhaps the same issue has been seen here as well.
