hi there,
i tryed imitate the winoze driver for my typhoon/anubis pencam (gt 8911
vidchip inside) connected on my usb root hub..,well this is my 1st try so i
need some help with this.. i sniffled the first usb ctrl blocks with bus
houd
-since sniffusb etc wont work - and got 7 control packets initializing the
cam to send data..
as said i tryed to send a usb_control_msg but got an invalid argument error,
may i switched the bytes and words wrong way? i tryed several versions but
suddenly uhci hangs :-// for this i used to compile with libusb..
by the way - where's the difference between usb_control_msg and
usb_bulk_write
may someone knows an answer
thanks a lot - jz
