Give us brainsss... er, I mean, dmesg. No way to tell what
subdriver ATEN is. And since you're on that, /proc/bus/usb/devices.

Hello All,
I'm using seven ATEN UC-232A USB-serial adapters on a 2.4.26 kernel and
have found that data read from any of these devices it littered with
NULs. For example, here's a sample from a Cisco router's boot sequence:
# cat /dev/usb/tts/1 > /tmp/o
# vi /tmp/o

Is this a linux-usb issue? I haven't seen or heard of it.

This patch reads the full 9 bytes of a configuration descriptor during
enumeration rather than just the first 8 bytes. That's how Windows does
it, and today I ran across a device that doesn't work properly when asked
to send only 8 bytes worth. I doubt very much this will cause any

There was, ages ago, but it's rather ancient by now.

A lot of people with USB controllers made by VIA have been suffering from
the fact that these controllers stop working when they receive a babble
packet. In particular, they stop generating interrupt requests. Since
the UHCI driver relies on IRQs from the controller for proper timing an

Hi,
the kobil_sct didn't work with uhci hcds.
It used usb_fill_bulk_urb instead of usb_fill_int_urb.
The attached patch fixes this.
It starts reading in open now - this gives apps (CT-API) the chance to
detect the p'n'p string correctly.
Greg, please apply.
