Problem Details: If successful, the usb_control_msg() function returns the number of bytes transferred. Fix up wb35_probe() to only bail out if the function returns a negative number. Also, fix up ieee80211_alloc_hw() error code to ENOMEM; otherwise GCC complains that err might be undefined (and is right about that). ...
