I get hard hangs with a Bt878 + disk activity (every time it hangs,
the disk activity LED is on).  But I don't have usb2.  However I have
a similar processor, Athlon XP 2100+, and motherboard, VIA KT333.
I'm also using reiserfs (where an OOPS occurred in your system logs).
I also have a realtek 8139 ethernet card.  We both have VIA usb 1.1
controllers.  My hangs happen with both 2.4 and 2.6 kernels.  I only
get hangs if I'm using the bttv card.

Are you sure you plugged your device into a usb 2 port, and not a usb 1.1 port?
Also, some products claim to be usb 2 devices, when they are in fact only usb 1.1.

1.1 devices would only get less than 1MB/s.

Ah, I misread it as 8 M bits / s, which is max 1.1 speed.

Bye, Duncan.

Normally I assume Mb/s is mega-bits and MB/s is mega-bytes. Of course I
guess the author of the post should clarify if I've made the wrong
assumption (and you didn't).

Is it possible that you are exceeding the capacity of your PCI bus?

Be careful about your use of terms.  Lots of people think USB-2.0 means
the same as high speed and USB-1.1 means full speed.  That's not right;  
it's perfectly legal for a USB-2.0 device to run only at full speed.

I guess so, but that's no reason to hang...  Or is overloading the PCI
bus somehow problematic?

Ciao,

Duncan.

Well it's certainly not good!  :-)

One of the failure modes that will cause an immediate shutdown of a USB 
host controller is a PCI error.  If the controller isn't working lots of 
bad things are likely to follow.  I can imagine that even if that doesn't 
happen, PCI errors could mess up other drivers or hardware too.

Updated kernel to 2.6.7, apparently bttv and pci overloading are not
issues here: I got usb2 to crash with nothing else loading the pci bus
except light network traffic. usb2 read speed improved from 5-15MBytes/s
to over 20MBytes/s when i switched it to a kt600 motherboard.
But still it's over 10MBytes/s less than the manufacturer's claimed
sustained data rate.

I connected the usb2 hard drive to the integrated usb2 ports on my
Gigabyte 7VT600-1394-KT600 motherboard:

Attached is the error messages from syslog when i was copying files to

Why do you say that you got usb2 to crash?  The log you posted clearly 
shows that the crash originated in the reiserfs code, caused by a series 
of I/O errors.

Your log doesn't give any indication why those I/O errors occurred; in 
fact it starts in the middle of the errors.  If you want to find out what 
really went wrong, you will have to turn on the usb-storage debugging 
option in your kernel's configuration.
