Thank you for your answer. I would like to add that the problem does not occur
in Ubuntu 10.10 neither, even if I use a USB hub. So, do you think that
updating the ehci_hcd driver can solve the problem?

I want to increase my default alsa buffer_size of 8192 to 32768 because
I'm sometimes getting small skips in my audio. Now, usually people use

Dear all,
I am using an external USB audio capturing device (XLR to USB converter)

arecord: pcm_read: 1692: read error: Input/output error
