Hi all,
I haven't been using Linux for long ,but I really like what I've got up and running so far. However I've got one problem I've been dragging around the forums for weeks now and it's taught me one thing, that USB and Linux are a pain in the (*).
System details
CPU: Intel Celeron (Coppermine) 601.425 MHz
Linux version 2.6.11-1.1369_FC4
Fedora Core 4
Problem...
I have a Epson CX1500 scanner/printer/copier which is six months old and runs well on this setup with a HDD with M$ Win98 installed.If however , I connect up the HDD with Fedora C4 ,an address bun fight starts as to IRQ's (Details below)
There is nothing wrong with the Epson unit ,under M$ it runs well(Shame, embarrassment)
It has been suggested , by /var/log/messages (See below) and members
of various forums that the IRQ address is indeed the problem.Is this likely, and might I have to change my BIOS/CMOS settings to run Linux properly. (Flame if you wish, but we were all babes once)
Here is perhaps a CLUE . If I run /var/log/messages and disconnect re-connect the Epson , two things happen...
Messages reports ....
<Date><Time> localhost kernel: usb 1-2: new full speed USB device using uhci_hcd and address 6
Note that during the boot bun fight listed below address 6 is never mentioned .AND at this time the whole system freezes. No input No output No mouse Cold Boot needed to roll again.
I have rolled this problem around various Forums and Mail lists for weeks now and am seriously considering changing distros and or offering a reward to anyone who can track this SOB problem down and throttle it.
Come on, I'm a newbie , gota be some Wizzard out there who can kill this before breakfast.
