Hi, recently I was working on porting EHCI HCD bus glue driver from the vendors kernel tree to the mainline [1]. I've got the storage (USB stick and USB external hard drive) working and was happy. However it does not work completely. Specifically something goes wrong if WiFi module is talked to. This WiFi module is on-board and connected through USB. The WiFi module is correctly identified and the rtl8192cu driver manages to output something, but issuing ip link set wlan0 up will cause an error, see the output of the dmesg [2]. Note, the same hardware works with vendor's tree EHCI bus glue driver and rtl8192cu, so hardware is ok. Maybe using a fact that my driver works for the storage but fails for the WiFi module you could help me identify the problem in it? By the way, the output of the lsusb -vvvv looks identical in both cases (with my driver and vendor's) [3].
