USB mouse over nanox

[Nabendu]

Anyone tried usb mouse over nanox (microwindow)?

It is crashing the ohci whenever i tried to run nanox as belows..

ohci_hcd 0000:00:01.1: OHCI Unrecoverable Error, disabled
ohci_hcd 0000:00:01.1: HC died; cleaning up
usb 3-2: USB disconnect, address 2
ohci_hcd 0000:00:01.1: leak ed 01860040 (#81) state 0 (has tds)


Anyone knows what may be the problem...

I had selected serial mouse in microwindow configuration.

Hi,

I'm using nano-x with that kernel version for 5475 and have seen something similar with the keyboard.
Do you see it by just having the mouse or other peripherals as well? I can trigger this with certain USB flash drives and it could be related to a potential USB1.1/2.0 problem in the kernel (check the kernel's bugzilla).

Are you just running OHCI or EHCI as well? Also, try another mouse or keyboard and see if the problem persists.

Good luck,
Andreas

There is a problem on PCI transfer, as well as USB stack implementation in kernel 2.6.25 release.
More detail - in DMA transfer.

I see. I believe I found something similar in the old 2.6.10 implementation of PCI.
What board are you using?

in 2.6.10 usb mouse,keybd, flash all are working... You have to use ohci and ehci both.


I am using 5475evb.
