Hello...
I have this problem when I submit a read URB. After
the submission, host controller does not enter the
dl_done_list( ) function which I think is responsible
for setting up the urb for the next read request. I
have no problems with the write process though. I
believe that the dl_done_list( ) function must be
called after submission of a read or write URB.
Because of the issue above, I cannot do anymore read's
from the usb channel.
What could be the reasons for not calling
dl_done_list( ) function after a urb submission???
I am using the generic usblp printer driver to receive
my read/write request from an application. I am
developing on an arm big endian platform with an OHCI
based usb hardware...
Thanks.
