Take care that you keep,
1. A 300ns delay between writing the command port and access to the data
port. and,
2. A 110ns delay between subsequent data accesses.

Subject: Re: [linux-usb-devel] ISP116
how fast is your strongarm processor? have you measured the
interrupt latency and the time it spend in the interrupt?
i have not used isp1161, but i have used cypress sl811, and i
have seen the same symptoms... having traced it with a usb traffic
analyzer, i found out my cpu was not fast enough
Hi,
I' ve modified Abraham vd Merwe's driver for isp1161 for memory mapped IO
to make it work with StrongArm on kernel version 2.4.18-rmk4.
When trying to connect a usb mouse I get the following output in the message
file:
hub.c: USB new device connect on bus1/2, assigned device number 2

Hi Christian!
I got the ISP1161 working on StrongARM, but I gave up on Roman's driver
early on. I'm using a slightly modified version of Philips' isp116x driver
(which is not too great either, but it works and is semi stable).
Hugo Fiennes also has another version which he claims to be working on
Hello,
I've modified Roman Weissgaerber's driver for isp1161 (0.9.5) for memory
mapped IO to make it work with StrongArms on Kernel 2.4.18.
Unfortunately this thing produces bunches of timeouts even on a stupid serial
device, e.g. a pl2303 usb2serial converter.
Timeouts mostly appear when I "cat
