OK, I recompiled the kernel to include only USB support, making usbserial and whiteheat loadable as modules (with verbose debugging defined).
I am loading them using "insmod usbserial debug=1" and "insmod whiteheat debug=1" as you suggested. The log file looks as it did before (White Heat converter now attached to ttyUSB0 ...). When I issue a cat "hi" > /dev/ttyUSB0, I get the same error message as before "cannot create /dev/ttyUSB0: Connection timed out". There are no additional messages written to the kernel log when I issue this command. Interestingly, if I do a "mknod ttyUSB93 c 189 0" where 189 is some bogus driver number, I get "cannot create /dev/ttyUSB93: error 19" and the kernel log shows "modprobe: Can't locate module car-major-189" which implies that linux is making the association between ttyUSB0, driver 188, and usbserial. thoughts?

Load the usbserial and whiteheat drivers with "debug=1": insmod usbserial debug=1 insmod whiteheat debug=1 and take a look at the kernel debug log when you try to access the port: cat "hi" > /dev/ttyUSB0 Let us know what it says. thanks, greg k-h p.s. linux-usb-* does not allow html messages, that's why you are getting filtered out. ------------------------------------------------------- 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
