I have just had occasion to do the above. These notes may speed someone through the same situation. The mobo is a 4 year old MSI MS-5184, a Baby AT form factor. It has two USB header pinsets (labelled JUSB1), but never had any socket plate attached to these. SuSE 8.1 was installed and running. First, catch your socket plate. An attractive front-located option is the Antec EasyUSB (http://www.antec-europe.com/a_easyusb.html#), which fits into a 5.25" drive bay, and provides two sockets, and mounting space for a 3.5" drive. In the UK, this is available from Ebuyer (www.ebuyer.com), price about £7. A back-located option is the Belkin USB Motherboard Dual Port Cable, F3U001(http://catalog.belkin.com/IWCatProductPage.process?Merchant_Id=1&Product_Id=17894). In the UK, this is available from Dabs (www.dabs.com), price around £7. Both options end in 2 x 5-point plugs for the USB pins, and the Antec site also has useful advice (http://www.antec-europe.com/products/easyusb/ezusb.html) on how to re-order the wiring to suit your mobo, if necessary. On this PC, I used the Antec option, which comes with a very generous length of cable which should fit the largest cases. Next, interrogate your mobo. I still had the manual for mine, and this gave a partial pinout description of the header pins. Power was on pin 1, followed by -Data, +Data, and two Grounds. The cable colours are, respectively, usually Red, White, Green, Black, but the second of the Antec plugs doesn't use these colours; nevertheless, both plugs have a Power label around the power cable, so that allows the plug to be inserted with the correct orientation. The problem with the mobo is that the pinout info doesn't say whether the second header has its power pin opposite pin 1, or opposite pin 5, ie is the sequence of pins the same for both headers, or is it reversed on the second? I suspect the first, but I solved this temporarily by not connecting the second plug (if anyone has any advice on which it might be, please let me know). In /etc/fstab, as root, add: usbdevfs /proc/bus/usb usbdevfs noauto 0 0 In /etc/sysconfig/hotplug, as root, change: HOTPLUG_START=no to: HOTPLUG_START=yes or else when you plug in a device you will get in /var/log/messages: "Setting up USB devices switched of[f]. Exiting usb.agent." As root, enter: mount /proc/bus/usb to mount usbdevfs. Then enter: modprobe usb-uhci The module usbcore is already loaded, and usb-uhci loaded with no errors. VIA chipsets, as on this mobo, are most likely to use usb-uhci, and the final proof was that usb-ohci refused to load. Then enter: rchotplug restart This should give the message that net, pci and usb are started. Now attach your device. The device in question was a Digital Dream l'espion digital camera, about the size of a matchbox, which was got as a kid's birthday prezzie from Tesco for £30 (http://www.digitaldreamco.com/shop/espion.htm). It only holds about 20 fairly low-res pics, but it has already been put to good use at school, I'm told! I had already tried this on a USB-enabled box, so I knew it worked, which narrowed down the possible problem areas! Attach the supplied USB cable to the camera, and then plug the other end into the top socket of the Antec faceplate (the bottom socket isn't connected to the mobo, remember). You should hear two beeps from the system, and then a longer beep from the camera. In /var/log/messages you should see something like: hub.c: USB device connect on bus 2/1, assigned device number 2 usb.c: USB device 2 (vend/prod 0x553/0x202) is not claimed by any active driver If you open usbview, you will see the new device, but it is listed in red, suggesting that the driver is incorrect. If anyone has any light to shed on this, I would be grateful, but it seems to work OK anyway, because in the meantime an icon for Still Camera will have automagically appeared on the desktop. Click on this, and then on the folder AEG Scan within, and viola! there are your pics. The simplest thing is to drag these into another folder, and then open them from there, because I can't figure out where the camera gets mounted - again, any enlightenment would be welcome. Hope this will be of interest to someone. Kevin
