Message:

Descriptor parsing modified (fixed)

• change usbkbd_parse_descriptors() not to parse class-specific descriptors as these are retrieved differently
• dump functions moved to descdump.h/c
• getting report descriptor in usbkbd/main.c
• changed descriptor structures (hid.h) to reflect, that there is only one report descriptor

File:

• uspace/drv/usbkbd/main.c (modified) (3 diffs)
