I have StrongArm SA1110 processor 133Mhz. I didn't measured the interrupt latency time and time spend in the interrupt, because i didn't get any interrupt from the host controller.
I have connected optical usb mouse, and LED indicator on mouse doesn't light. It seams that host controller doesn't send anything to the device. The D+ line is always 0 V. D- line is on 3 V (Low speed device). -----Original Message----- From: Thomas Chen [mailto:[EMAIL PROTECTED] Sent: Tuesday, March 11, 2003 4:35 PM To: Boris Stuhec; [EMAIL PROTECTED] Subject: Re: [linux-usb-devel] ISP1161 and StrongArm 1110 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 and the interrupt latency was too long... (when my sof interrupt comes around, by the time i do something.... the frame time is half over) on 3/11/03 1:58 AM, Boris Stuhec at [EMAIL PROTECTED] wrote: > 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 > usb_control/bulk_msg: timeout > unlink URB timeout > usb.c: USB device not accepting new address=2 (error=-110) > usb_control/bulk_msg: timeout > unlink URB timeout > usb.c: USB device not accepting new address=3 (error=-110) > > Who's got an ISP1161 working on a StrongArm? > Regards > Boris > ------------------------------------------------------- > This sf.net email is sponsored by:ThinkGeek > Welcome to geek heaven. > http://thinkgeek.com/sf > _______________________________________________ > [EMAIL PROTECTED] > To unsubscribe, use the last form field at: > https://lists.sourceforge.net/lists/listinfo/linux-usb-devel > ------------------------------------------------------- This SF.net email is sponsored by:Crypto Challenge is now open!
