You may be able to work around this by passing the noapic boot option to your kernel, or when you’re using an add-in PCI card moving the USB adapter to some other PCI slot. A user reported this. It might be labelled as USB, or it might be more obscure, discussing Plug-n-Play, or having options for various types of operating systems. Note that in the 2. You should then follow the USB Guide to setup your device. The “lsusb” output is far more detailed and informative.

Many Epson printers the does not need a special set of characters sent to the printer for it to use the USB interface.
The devices are named by a scheme like this:. There are two ways to see these messages, which are shown the opt way that other kernel debug messages are shown. One basic thing is to make sure you make sure there are no dependencies on particular host controller hardware or drivers. If you have access to such equipment, please mention it. Avoid reporting problems except with kernels from kernel.
Switch to a different USB connector on your computer. But other devices can and do have multiple interfaces and sometimes multiple configurations.

First opfn sure that it’s a bug coontroller hasn’t yet been fixed. That’s a common way for driver bugs to panic kernels, and there are at least three different scenarios to test: It affects handling of low speed devices such as some mice and keyboards when they’re connected to the root hub. You should be using the hotplug scripts. First the backward-compatible way: You’ll find a patch suitable for 2.
If you are sure that you actually have a suitable hardware setup, look for a BIOS option opti 82c861 pci to usb open host controller could be applicable. At this writing the EHCI driver is labeled “experimental”. If the problem comes up using EHCI, try to reproduce it using one of the other controller drivers e.
As the name implies this transfer length is measured in sectors, where a sector is bytes that’s a logical sector size, not necessarily the same as the size of a physical sector on the device.
Does Linux talk fo USB 2. You can use dmesgor syslog. The result is that data transfers fail and nothing can be written to the disc. If there’s any question, just include lspci -v output. I have hos read one, and thought it opti 82c861 pci to usb open host controller very poor. You may find this testing information page to be useful.
If it pcu, there are two ways of solving the problem. This prevents usb-storage from automatically detecting all the devices in your removable storage device. This acts just like the interface in an actual hub an almost every respect; see below.
A patch may be added to kernels later than 2. If you find that you have a workaround, please still report the problem! Another is to make sure you test unplugging the device.
You can do this using a uniprint – stcany. I’ve collectioned their notes here. You should then follow the USB Guide to setup your device. This makes sure the modules I need for my joystick and printer are loaded, if you modify your system startup to “modprobe usb”.
See the kerneldoc “make htmldocs” in the root of your kernelopti 82c861 pci to usb open host controller should be relatively complete in current 2. Opti 82c861 pci to usb open host controller front panel connector probably doesn’t use cabling designed with USB in mind; and its cable could be damaged by bending, baking or something else even when it’s not routed through the power supply.
If opit are using Linux 2. It happens to be a hub, and ” In your boot controoller or initial RAM disk you need to include support for all the needed items to support using a USB disk.

So the interfaces show up as. You probably need to load those drivers as modules, in which case lsmod will tell you whether it’s already there or not.
And make sure you say which HCD s you’re using. You need to build a kernel with support for USB.
