Title: Since update to SME 8 / Pb with USB Backup
Post by: dadou on April 25, 2014, 08:08:15 PM

Hello,

Since I updated to SME 8 I have a problem with my usb backup (on SME 7 it was working fine).
It seems that there is problem with the USB support.

When I use the disk on another system it works fine. Here are my logs :

I suppose it's a problem of compatibility between kernel and the USB chipset of the motherboard ?
What do you think I should do ?

Thanks,

David

If isn't hardware problem (old machine) you can try with this (http://www.cyberciti.biz/faq/rhel-redhat-centos-kernel-usb-reset-high-speed-ehci_hcd/) istruction and force USB to work with 1.1 standard, but don't know how can apply this on the SME-way...

Thanks for your answer.

No it's not hardware problem I think. And my USB controller is USB2 :

lspci | grep USB
00:1a.0 USB controller: Intel Corporation 5 Series/3400 Series Chipset USB2 Enhanced Host Controller (rev 06)
00:1d.0 USB controller: Intel Corporation 5 Series/3400 Series Chipset USB2 Enhanced Host Controller (rev 06)
02:00.0 USB controller: NEC Corporation uPD720200 USB 3.0 Host Controller (rev 03)

USB2 was not supported on SME 7 ? Because it was working perfectly before update.

Google for:

reset high speed USB device using ehci_hcd and address

and you'[ll find lots of information to digest, including lots of suggestions, e.g. unplug/replug the device, use a different cable, set irqpolling, set the device to a lower max_sectors, etc.

Thanks Charlie,

I found the solution. Just needed to update the bios of the motherboard.
Everything is running fine now.

Thanks for the advice.

Thanks for the update and final solution dadou.

Could you also change the initial subject and add [SOLVED] to it?

Cheers,

Sorry but it seems I can't make any modification on my initial post. I don't have the modify option on this one. So I can't change the subject.
