Hello, I just upgraded my IBM Thinkpad T40p from 2.4.23 to 2.6.1rc1. All seems well, except for USB, which is excruciatingly slow after the upgrade.
I am using my Sony Clie NX-70V as my USB device. It can operate in two modes: as a Palm device (using the standard pilot-link package and the Visor serial driver in the kernel) and a standard mass storage device, which lets the PC mount its memory stick. I have used it in both modes for some time. Since the upgrade to 2.6.1rc1, I first tried the mass storage mode. I observed that performance was bad -- probably 5 times slower than with 2.4.x. Moreover, pilot-link coredumped on my once, and I had to turn off the Palm to get it out of confusion. When next I tried to use USB, my system froze hard -- no messages, and even magic sysrq could not recover it. Performance with pilot-link is even worse, but seems to be randomly so. Sometimes, it performs almost normally; other times, it is a terribly slow performer indeed, taking many minutes to complete what should be done in about 10 seconds normally. I have not much to report as far as diagnostics go; but dmesg did note this: hub 2-0:1.0: new USB device on port 2, assigned address 10 usb 2-2: control timeout on ep0in usb 2-2: palm_os_4_probe - error -110 getting connection info usbserial 2-2:1.0: Handspring Visor / Palm OS converter detected usb 2-2: Handspring Visor / Palm OS converter now attached to ttyUSB0 (or usb/tts/0 for devfs) usb 2-2: Handspring Visor / Palm OS converter now attached to ttyUSB1 (or usb/tts/1 for devfs) lspci notes this for my system's USB controller: 00:1d.0 USB Controller: Intel Corp. 82801DB USB (Hub #1) (rev 01) 00:1d.1 USB Controller: Intel Corp. 82801DB USB (Hub #2) (rev 01) 00:1d.2 USB Controller: Intel Corp. 82801DB USB (Hub #3) (rev 01) 00:1d.7 USB Controller: Intel Corp. 82801DB USB2 (rev 01) I have these modules loaded: $ cat /proc/modules | egrep -i 'usb|hci' usb_storage 44480 0 - Live 0xe09d0000 usbserial 29552 3 visor, Live 0xe0997000 scsi_mod 108216 4 ide_scsi,usb_storage,sr_mod,sg, Live 0xe09a5000 usbmouse 5760 0 - Live 0xe0902000 usbkbd 7424 0 - Live 0xe08ff000 uhci_hcd 30096 0 - Live 0xe0905000 usbcore 105052 9 hid,usb_storage,visor,usbserial,usbmouse,usbkbd,uhci_hcd, Live 0xe091a000 Thanks for any help. -- John ------------------------------------------------------- This SF.net email is sponsored by: IBM Linux Tutorials.
