Have you by any chance rolled your own kernel? There is an option in more recent 2.6 kernels, something along the lines of "low speed USB storage" or something like that, which causes that type of behaviour. Just a guess... Hans

I will definitely agree with you on ***SLOW*** usb transferts. I have had the same problem through all of the (Open)SUSE 10 versions (both with both default and homemade kernels) that I have tested (on two different computers). I figured that it might be more related to the type of pendrive, because no one else seems to have noticed. My pendrive is a Crucial Gizmo! 1GB. It is so slow that I have to boot into Windows some times (when I don't have the time to copy my files to my pendrive in the mornings) so that I won't be late for work ;) Other than that I get around the slow transfert rates my copying files across the network via scp. @+ James

I have the same problem with a Memorex 2 gig USB 2.0 stick. When I read from it, the speeds are fine, but if I try to copy TO it, I'm getting rates of under 10K bytes/sec.

Yes that is exactly my problem too. The key words are *** 10K bytes/sec ***. Maybe the size is more important than the manufacturer itself.

I have the same problem with a 64 MB USB pen (can't remember the manifacturer), an Olidata 128 MB USB and a Nilox 1GB USB2. All those devices work well with other linux distro. I don't think the problem is size related but I haven't yet tried to recompile the kernel as suggested by Haans.

I Dunno James, I haven't tried the pendrive on 10 yet. I just installed it last night. On 9.3, my kingston datatraveler 1GB drive is fast as lightning. I will try it on 10.0 tonight and report back. -- David C. Rankin, J.D., P.E.

No idea - looks like a serious bug in SUSE 10 - I've just been bitten by it. I've just upgraded from 9.3 where my usb 2.0 Cowon Iaudio G3 worked perfectly - sustained transfer rates of 1.8 - 2MB per second. Under SUSE 10, it's 36-40 kb/s. Same hardware, connections - just upgraded the OS. Now it takes hours to transfer a 300MB audiobook. I did a search for usb performance on opensuse.org and it came up with a link to the most annoying bugs page - which in turn links to: https://bugzilla.novell.com/show_bug.cgi?id=105871 There's a workaround about halfway down the bug report to disable syncing - and it works for me, speeds things up immensly - but it's not terribly smooth as it causes konqueror to apparently hang while the usb drive finishes actually writing the data. It's definitely a regression compared with 9.3. A shame, because the rest of the install went really smoothly. Jason
