SoC's with USB host
by Jamie Guinan June 10, 2006

June 10, 2006

To follow up on discussion about USB capabilities, I took a quick look at which platforms support USB host (so you can plug webcams, etc. *into* it), $ cd linux-2.6.16 $ find . | grep ohci ... ./drivers/usb/host/ohci-s3c2410.c [ Samsung ARM 920T ] ./drivers/usb/host/ohci-sa1111.c [ StrongARM(SA1110) companion Chip ] ./drivers/usb/host/ohci-lh7a404.c [ Sharp ARM920T ] ./drivers/usb/host/ohci-ppc-soc.c [ Various PowerPC (Freescale) ] ./drivers/usb/host/ohci-au1xxx.c [ AMD (formerly Alchemy) MIPS Au1000 ] ./drivers/usb/host/ohci-pxa27x.c [ XScale ARM (successor to SA1110] ... Those modules are thin hardware-specific glue around the main ohci/usb kernel code. I think the gumstix is a pxa25x, and only the 27x supports USB host. Development boards for a lot of these are priced rather high for the typical hobbyist budget, from a few hundred $$ on up, http://www.embeddedplanet.com/products/sbc.asp http://dkc3.digikey.com/PDF/T062/0378.pdf http://www.hitechglobal.com/boards/ARM920T.htm It looks like Gumstix and routerboard are the cheapest available products in this class. And they're great, but hopefully in the we'll see more things aimed at hobbyists, with USB host capability. -Jamie

Problem with usermod
by Chuck Noyes June 4, 2006

June 4, 2006

Hi All, I'm running ubuntu (brezzy), and I just shot myself in the foot.... I went to add my username to a new group, but forgot to include the other groups that I belong to in the command. The command I used was 'sudo usermod -G <new-group> <my-username>'. Now I only belong to <new-group>. That removed my username from the other groups I belonged to, including the admin group. Is there a way undo what I did? I do have a copy of /etc/group before the change. Thanks, -Chuck

Booting Mepis from USB cd rom
by Sean Flynn June 1, 2006

June 1, 2006

Just acquired a new laptop that doesn't have an internal cd rom drive, just a "d-bay" usb cd drive. I had been using Mepis on my previous laptop, and I enjoyed it. But the Mepis Live CD chokes when I try to boot from it. The cd does boot in other pcs, so the media is good. I checked my bios boot settings, but I can boot Knoppix and Ubuntu live cds. I figure that to get other Mepis booted there must be a cheat code I can pass, but my little bit of googling didn't help. Couldn't find anything on the Mepis forums either. Could anyone explain what's going on, or point me somewhere for more knowledge on it. I'd like to understand more how a live cd boots and what the difference between a usb cd and an internal cd rom drive are.
