Very slow USB transfer speeds - Ubuntu only
Help! I'm at the end of my rope here. And the most frustrating part is, I've found many posts all over the web from others who have had similar problems, but they ALL seem to be older distros and those solutions don't work for me. "Find Similar Threads" only yields one thread, and I don't have the file mentioned in the answer (the original poster didn't either).
EDIT: Found it. But the proposed solution was to make sure that CONFIG_USB_EHCI_TT_NEWSCHED=y was set. Mine is.
Computer: AMD 64 Quad core, USB 2.0 on front bus, dual booting Vista and Ubuntu 10.10
Device: New Sansa Clip+ 8GB mp3 player
Problem: When I transfer files to my mp3 player in Ubuntu, I max out at about 150 KiBbps. It's painfully slow - it takes me half an hour to transfer 300 MB worth of albums. I had similar problems with an older player that may have been usb 1.1, but this one is brand new. And when I switched to Vista (first time in months, thankfully), I was able to transfer the same files at upwards of 3 MBps. I know that flash devices often can't write anywhere near the max speed of USB 2.0, but obviously it can do a whole lot better then 150 KiBps!
So, same hardware, same files, different OS - the problem must be with my Ubuntu config.
