Hi, I'm trying to get an ide harddrive with a 160GB reiserfs partition in an external external usb 2.0 case working on my Thinkpad with custom built 2.4.31 kernel. I tried different cases in a computer shop. Copying files between internal and external drive seems to work fine for some time (or some 200 MB transferral), but then it gets terribly slow. I can't do any thorough testing in the shop therefore I like to find out through the list.
1. The module used seems to be uhci, although in the beginning it seems to utilize full bandwidth (if that's not the noflushd). I can't enable ehci-hcd in the kernel config of 2.4.31; make menuconfig doesn't show ehci at all, make xconfig shows it greyed. I can enable it manually in the .config file and it gets compiled and installed but I wonder why it is grey in the first place. Can the uhci driver in 2.4.31 handle high bandwidth (420 Mb/s) USB 2.0 all by itself? Unfortunately I didn't check /proc/bus/usb/devices and can't send it to the list as I don't have the extenal case here. 2. After it slows down, I get these kernel messages: Aug 27 13:56:12 grisey noflushd[1092]: Could not stop kupdate. Expect lousy spindown times: No such file or directory Is that a symptom or is noflushd the cause of the slowdown? I read something in the noflushd faq saying that it won't handle reiserfs. thanx for any help, Orm ------------------------------------------------------- SF.Net email is Sponsored by the Better Software Conference & EXPO September 19-22, 2005 * San Francisco, CA * Development Lifecycle Practices Agile & Plan-Driven Development * Managing Projects & Teams * Testing & QA Security * Process Improvement & Measurement * http://www.sqe.com/bsce5sf _______________________________________________ Linux-usb-users@lists.sourceforge.net To unsubscribe, use the last form field at: https://lists.sourceforge.net/lists/listinfo/linux-usb-users
