I believe that's your firmware problem
Download USB Command Verifier from http://www.usb.org/developers/tools/ and
make sure that your device passes all tests; use CATC to debug issues

Hello Sir
In our company , We are doing the HCT12.1 test for one USB device.
In the test process for "USB adress description test" "USB
description test" "USBdevice control request test" "USB enuneration
stress test"
We all meet the same problem. When we start the test operation and
view the debug message
output from driver , It shows:
after normal initialize . the driver calls
IRP_MJ_PNP ,minor IRP_MN_QUERY_CAPABILITIES
IRP_MJ_PNP ,minor IRP_MN_QUERY_BUS_INFORMATION
IRP_MJ_PNP ,minor IRP_MN_QUERY_DEVICE_RELATION
then following with:
IRP_MJ_PNP ,minor IRP_MN_QUERY_REMOVE_DEVICE
IRP_MJ_PNP ,minor IRP_MN_REMOVE_DEVICE
BulkUsb_StopDevice
BulkUsb_RemoveDevice
BulkUsb_Unload
then HCT start doing device descriptor enumeration many times but
stops at some point.
waiting forever . the HCT test process can not be finished.
What is the reason for this issue ?
Why HCT unload the driver before it performe device descriptor
enumeration .
If it is our driver 's problem or it is the device firmware 's
problem
Thanks a lot
.
