Speaking of PC accessories, we recently purchased a 6 port USB 2.0 card off of Ebay for $10. The board came with two USB cables and a box that was intended to be placed in a drive bay for front-panel access to 2 of the ports; however, it works equally well if you run the cords out of the back of the CPU and put the bay on your desk. All the card says on it is USB 2.0 PCI TO USB 2.0 Card. The packaging is generic as well. It turns out that this is an model HE460A H_E brand device made in China by Shunde ZhuoHua Electronic Co Ltd. Here is a link to the product details.

We have an embedded USB controller on our motherboard from 2001. It turns out that the USB driver is different than the driver for the new card. Not a surprise, really, but kind of annoying. After installing the PCI card and rebooting, we were unable to see our Freecom USBCard. The whole idea of the expansion card was so we could plug in the Freecom card quickly and easily. What to do?

What to do? Recompile the Linux kernel, of course. We like to stick the USB stuff in the kernel, not as modules. It works better... well, Agatha thinks so... Urbana probably wouldn't do it this way... she certainly has no problem using the printer hooked up to Agatha's machine, though. Anyway, the key thing is to add these config options to the kernel:

CONFIG_USB_EHCI_HCD=y CONFIG_USB_OHCI=y

We previously just had:

CONFIG_USB_UHCI_ALT=y

Here is Agatha's .config file for 2.4.25. This works with many USB devices, including an HP 1200 Printer, a Handspring Visor, a Sony Cyber-shot model DSC-U20 camera, and the Freecom USBCard. It handles both the embedded USB controller on the motherboard, and our new controller. The kernel is 1.2 megs. A lot of stuff is embedded in the kernel. Again, Agatha *likes that*.

Here are some interesting entries from dmesg:
