Hi,
I have a low speed display device with just a control endpoint. When some
large data is sent on the control endpoint, it is able to ACK for first
data packet in a frame, but it NAKs for the next data packet so the rest
of the frame goes waste because UHCI doesn't schedule any other TD in that
frame.
In UHCI driver (usb-uhci.c), I tried inserting TDs with 0 byte of data in
between 2 genuine TDs for that device but the device NAKs even for a 0
byte data packet.
Is there any way to introduce some sort of delay between 2 TDs so that the
device gets time to process the first one? any other suggestion pls?
Manoj
