Description Jakob Petsovits 2005-09-15 03:42:50 UTC
Distribution: Gentoo   
Hardware Environment: Acer TravelMate 803LCi  
  
Problem Description:  
  
I recently bought a usb 2.0 stick, 512 MB, branded by Ultra-Media.  
The Linux kernel only runs it as a usb 1.1 device,  
whereas in Windows XP it works with full usb 2.0 speed  
(and without installing additional drivers there),  
so I think this should be a kernel problem.  
  
KInfoCenter reports the device with the name "Unknown" in the  
"Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M)  
 USB UHCI Controller #x (x)" bus (x == 1..3), which is 1.1.  
The usb 2.0 bus would be "Intel Corporation 82801DB/DBM  
 (ICH4/ICH4-M) USB2 EHCI Controller (4)", this is where  
other usb 2.0 devices are put into (for example, my  
external hd or other usb sticks work, just not this one).  
  
As for the device details, KInfoCenter says:  
  
Class:       0 ((Defined at Interface level))  
Subclass:    0  
Protocol:    0  
USB Version: 1.10  
  
Vendor ID:   0x9a6 (Poinchips)  
Product ID:  0x8001  
Revision:    1.00  
  
Speed:       12 Mbit/s  
Channels:    0  
Max. Packet Size: 0  
  
When plugging in, dmesg says: 
 
usb 1-2: new full speed USB device using uhci_hcd and address 3 
scsi3 : SCSI emulation for USB Mass Storage devices 
usb-storage: device found at 3

What can I do to help fixing this? (Not being a kernel hacker, you know.)  
  
  
Steps to reproduce:   
- Plug the usb stick in  
- See the device properties, I use KInfoCenter,  
  but I'm sure there's some files in /proc too
Comment 1 David Brownell 2005-09-15 12:12:11 UTC
Are you sure you loaded "ehci-hcd"?  Normally that 
should be the "usb1" bus, but not here.  That suggests 
you don't have the right drivers loaded. 
 
If you have, then please update this report to include 
"dmesg" output for (a) starting up EHCI, and (b) plugging 
in this device, which will first include EHCI messages. 
Make sure to build your kernel with CONFIG_USB_DEBUG. 
Comment 2 Greg Kroah-Hartman 2005-09-15 15:35:13 UTC
Can you provide the output of 'mount'?
Comment 3 Greg Kroah-Hartman 2005-09-15 15:36:15 UTC
Oh, can you also provide the output of 'cat /proc/bus/usb/devices' with 
the device plugged in?
Comment 4 Jakob Petsovits 2005-09-16 01:52:18 UTC
(1 of 3) 
Here's the dmesg output. I have removed output from the other devices and 
marked what belongs to the booting process and what comes when plugging in the 
stick. As you can see, ehci-hcd is loaded properly and already before the stick 
is plugged in. I could maybe also mention that the issue has also been present 
in 2.6.12 already.

The output of 'cat /proc/bus/usb/devices', which is obviously the source of 
information for KInfoCenter (from where I copied the information in the first 
comment of the bug report). The stick is the 4th entry.

The output of 'mount'. I've got 2 partitions on the stick, 
neither one shows any errors or non-standard stuff when mounting. 
 
$ mount -v /dev/sda1 
/dev/sda1 on /media/USB-DATA type vfat 
(rw,nosuid,nodev,sync,noatime,utf8,user=jakob) 
$ mount -v /dev/sda2 
/dev/sda2 on /media/USB-OS type vfat 
(rw,nosuid,nodev,sync,noatime,utf8,user=jakob)

This is why your device is so slow, the "sync" option.  Disable that and
your device should be a lot faster.

1. Thanks, you're right. Even if the entry in fstab, along with its options, is 
generated automatically with HAL and the KDE media:/ ioslave, but it doesn't 
have to concern you kernel devs how I manage to get an entry without 'sync'. 
 
2. But, even if fast enough without 'sync', that doesn't explain why the stick 
is only running in Full-Speed USB 1.1 mode instead of Hi-Speed USB 2.0. Do you 
think it's really a 1.1 stick (even if indicated otherwise on its packaging)? 
Anyways, I have to get back to Windows to check if it exceeds a speed of 12 
Mbps there (which is of course not happening in Linux, even without 'sync', 
because it's recognized as 1.1 device). 
 
Sorry if I'm wasting your time with a moot problem, in case it is one.

No, your device is USB 2.0 compliant, just the "full speed" portion of that
spec :(

Yeah, it's very confusing, and you aren't the first one to be caught by 
companies not being entirely honest in their advertising, numerous
printers are also like this.

From what I can see, yes, your device is running as fast as it can.

Ok Greg, thanks very much for your time, insight and explanations :) 
I'll see what I'm going to do with that knowledge...
