Hi,
I'm writing a new usb-storage subdriver to support card readers based on the
Alauda chip.
I've sniffed some data and I am building up an idea of how the thing works. I
have attempted to put pen to paper but I am having trouble sending anything on
the control pipe.
When I plug it in, I get:
usb 2-3: new full speed USB device using ohci_hcd and address 24

usb-storage: Status code -32; transferred 0/2
usb-storage: -- stall on control pipe
usb-storage: init_alauda: ctrl #1 failed
I have attached the early driver file used to make this happen. It includes an
ugly hack to get the second bulk command going out of EP1 (the send_bulk_pipe
goes to EP3) -- I'm not sure what the bulk commands do at this stage, or if
they are even needed. However, whether they are there or not, I always get the
control pipe stall :(
I have also attached the beginning section of the sniffed data that I am
trying to copy!
I'd be very grateful for any help getting this off the ground.
Thanks!
Daniel
