Difference in FX2/FX2LP reported pipe order between USB 2.0 and USB 1.1 hosts
In dscr.a51, my pipes are defined as:
pipe0: endpoint 2 OUT
pipe1: endpoint 1 OUT
pipe2: endpoint 2 IN
pipe3: endpoint 1 IN
On a computer with USB 2.0, everything is okay (i.e. all pipes are reported correctly and in the right order), but on a computer with USB 1.1, the pipe order changed to:
pipe0: endpoint 1 OUT
pipe1: endpoint 1 IN
pipe2: endpoint 2 OUT
No matter how I change the dscr.a51 (different order, less endpoints), there are always 3 pipes and endpoints reported on a USB 1.1 host. What could be the problem?

EZ-USB.SYS Does not Support Overlapped I/O
I am trying to do overlapped I/O for the DeviceIoControl call. It is performing CreateFile calls with the file overlapped flag. The problem is that the code in DeviceIoControl never exits, even though it is called with the overlapped I/O flag. Could it be that there is no support for that in the ezusb.sys driver?

FX2 enumerates as an HDTV device
When I plug in my FX2 device (no EEPROM) it is recognized as an HDTV device. I cannot use my host application to communicate with the device even though I have the Cypress VID/PID bound to my driver using the format as shown in ezusbw2k.inf.
Why is my device recognized as an HDTV? How can I fix this so that FX2 uses my driver and my host application can communicate with the device?
