Hello folks, for some confidential reason, I need to disable the USB to access the storage devices in Suse11.2, but I still need two USB for the mouse and keyboard. Anyone knows?
Thanks a lot in advance! (3 Replies)

While I know that it's possible to use something like SANE to share a USB scanner over a network, or use NBD or iSCSI to share a USB flash or external HD over the network, I've been wondering about a raw USB <--> TCP/IP transport. Back in the late 90s, I swear I remember hearing about a project... (2 Replies)

I am trying to get a flash card reader to work with my machine. My question is, are all of my USB ports screwed up? Do I need to buy a seperate USB controller? I does not appear that the onboard USB ports work.
In trying to get it to work, I typed cat /proc/scsi/scsi and got this:

EHCI(4) BSD Kernel Interfaces Manual EHCI(4)NAME
ehci -- USB Enhanced Host Controller driver
SYNOPSIS
device ehci
DESCRIPTION
The ehci driver provides support for the USB Enhanced Host Controller Interface, which is used by USB 2.0 controllers.
EHCI controllers are peculiar in that they can only handle the USB 2.0 protocol. This means that they normally have one or more companion
controllers (i.e., ohci(4) or uhci(4)) handling USB 1.x devices. Consequently each USB connector is electrically connected to two USB con-
trollers. The handling of this is totally automatic, but can be noticed since USB 1.x and USB 2.0 devices plugged in to the same connector
appear to connect to different USB busses.
SEE ALSO ohci(4), uhci(4), usb(4), xhci(4)HISTORY
The ehci device driver first appeared in FreeBSD 5.1.
LOADER TUNABLES
When the kernel has been compiled with options USB_DEBUG, some tunables become available that affect the behavior of ehci. These tunables
can be set at the loader(8) prompt before booting the kernel or stored in loader.conf(5).
hw.usb.ehci.lostintrbug
This tunable enables the lost interrupt quirk. The default value is 0 (off).
hw.usb.ehci.iaadbug
This tunable enables the EHCI doorbell quirk. The default value is 0 (off).
hw.usb.ehci.no_hs
This tunable disables USB devices to attach like HIGH-speed ones and will force all attached devices to attach to the FULL- or LOW-
speed companion controller. The default value is 0 (off).
