USB composite device, enumerate WINUSB and CDC two devices, win10 enumeration system don't need to install the driver by the way,
To winusb device access:
CreateFile to success and failure WinUsb_Initialize
Quote error: 8 ERROR_NOT_ENOUGH_MEMORY

If only single winusb device enumeration, access right,
I use the bus hound reading and writing are no problem about it,
Is the winusb open, no, data didn't check for three days, ask ace to help!

WinUSB Win10 don't support?

CodePudding user response:

Support, but the enumeration into two equipment, can't open the winusb communicate

CodePudding user response:

No help?

CodePudding user response:

No, CreateFile, called after the first sentence, I worry about is hardware fameware inside, equipment descriptions have a problem
