I am using Lothar's isp1362-hcd.c driver on a 2.6.16 kernel and a

I got the driver to semi work and it is talking with the chip, best I

Hi,
We have a Cypress based usb keyboard software that enumerates as a
USB Keyboard and works properly in Windows 32 / 64 bit platforms.
When it is connected to Linux, the device enumerates as a keyboard
with proper configurations. But whatever keystrokes we send to the
host are lost. I have

Possibly. How about dumping the QH and its associated QTDs when the
driver unlinks it? Then we'd be able to notice various mismatches.

Hi ,

Hi,
I am using Sony Ericsson DCU-11 Cable (alongwith SE K300i mobile)on
Linux 2.6.16-1.2122_FC5.
Long time I could not get this cable work on Linux. But when I tried with
modprobe usbserial vendor=0x0731 product=0x0528
I got it detected and working for sometimes.
However what I find very strange i
When closing the device, the driver acquires/release twice the
port lock before/after waiting for the data to be completely
sent. Therefore it will dead lock.
This patch fixes it and also uses the generic scheduler services
for waiting for an event.

Here are the results again.
The few transactions for the time period before the "command_abort called" are
typically like below
1. Host sends 512 bytes OUT packet which is ACKED.
2. Host sends 13 bytes IN packet which is ACKED.
3. Host sends 31 bytes OUT packet which is NYETD.

The PNX8550 OHCI is a platform device so we better include the necessary
headers.
