Hi,
I'm working on a CEPC platform for a Panel PC based on an SBC83675 board.
The board has a Celeron 1.2 gHz processor and uses the VIA VT8606
"Twister-T" chipset. It provides two USB 1.1 ports. I started with the
Industrial Controller platform and added the features I needed from there.
I can plug a USB 1.1 compact flash reader into the system with no
difficulties. However, if I plug in a USB 2.0 compact flash reader, it is
not recognized. Debug messages show that the connection process gets to the
point where the Usbdisk6.dll is loaded but the process fails shortly after
that. The first significant debug message is:
BOT_DataTransfer warning(6.7.2.3, RequestLength:8 TransferLength:4 Err:0
UsbErr:0x0, dwTimeout:5000)
Up until the failure occurs, the debug messages from inserting the 2.0
device match the debug messages generated by inserting the 1.1 device.
Should the CE 5.0 USB driver support working with USB 2.0 devices when the
system chipset has USB 1.1 hardware? If I boot the system to MSDOS, it
recognizes the USB 2.0 reader properly. Has anyone had success with this
configuration?
I've searched through the archives and haven't found anything that has
improved the situation
Thanks,
Jim
