Hello again, some things to add.

That should have say: "wValue & 0x00ff" to mask the strange "f" either. Okay. To check that the descriptor looks good from host side, I did "rmmod usbcphost" and this is what it says after plugging in the device: Oct 30 13:37:39 linux_wessler kernel: usb.c: USB device 9 (vend/prod 0x10d1/0x202) is not claimed by any active driver.
