The driver you are using is a basic version; I've just completed an up to date version which will be released shortly once it's done QA. > I compiled USB support, USB Serial Converter support, > and USB ConnectTech WhiteHEAT Serial Driver support Correct. > into the kernel.Upon rebooting, the kernel log showed > that the USB device was not claimed by any active > driver. I then compiled "Support for hot-pluggable This is sometimes misleading; the usb core can report not claimed faster than the hotplugging system can load the usbserial and whiteheat modules. > I am not using hotplug support (I do not have any > hotplug scripts loaded) in my configuration.

Please contact myself or support ([EMAIL PROTECTED]) directly to open a call. Otherwise I'll look at it in my CFT. :-) > Tyrone Bekiares > Senior Software Engineer > Motorola, Inc. I'm curious what you're using the WhiteHEAT for? ..Stu -- We make multiport serial boards. <http://www.connecttech.com> (800) 426-8979 ------------------------------------------------------- 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-users
