Denny, When you report problems like this, please include some information that tells what the usb-ohci driver is doing. Specifically, please enable DEBUG up at the top of usb-ohci.c and let us know what errors that driver reports. That should produce "kern.debug" messages through "dmesg" or syslogd, which will have information that helps us to find out what's realling going wrong. - Dave > From: "Denny Fox" <[EMAIL PROTECTED]> > To: <[EMAIL PROTECTED]> > Date: Mon, 26 Feb 2001 12:19:33 -0600 > Subject: [Linux-usb-users] Bug with usb-ohci.o and Ricochet acm wireless modem > > I'd like to report a problem with usb-ohci.o when used with the acm.o > module and a Ricochet wireless modem. > > Summary: > The Ricochet wireless modem works with Intel USB uhci.o but fails with > ALI and other ohci USB controller hardware.
