Cannot Open /proc/bus/usb/devices No Such File Or Directory
VMware Workstation 6.5.x has had no problem with USB devices on any of these versions of Ubuntu.

Then comes the sequence of port numbers for each of the intermediate hubs along the path to the device. If your software is using /proc/bus/usb, it is broken -- you've had over a year to change it, and you've failed to do so. http://scriptkeeper.net/cannot-open/cannot-open-proc-bus-usb-devices.html
Unless there is some over-arching reason *not* to use usbfs then the best solution is, I think, to amend /etc/init.d/mountdevsubfs.sh so instead of: # # Magic to make /proc/bus/usb work # You also might want to look at the Linux USB scanner FAQ. Such a library is in my opinion a correct way of dealing with legacy devices which are lacking in current kernels (keeping the support in the kernel after its sell-by date BIOS Support to boot from USB Kernel support for USB Storage (including SCSI) A patch to delay boot process The first of these is something outside your control, either your BIOS their explanation
As the name implies this transfer length is measured in sectors, where a sector is 512 bytes (that's a logical sector size, not necessarily the same as the size of a It is an ASUS P7H57D-V EVO I tested the boot media on another workstation (a Dell Optiplex 745) and it does not get the error. There does seem to be a bios update for linux on this board.
So you're right: I got caught by a documentation error, and did not try running it without first trying to meet the documented requirements, although even there the documentation is ambiguous What are the sysfs structures for Linux USB? usbview may be different (I have not investigated this package). I tried disconnecting the HDDs on both the ASUS P7H and the Optiplex, Optiplex will run fine in read-only mode but the P7H still gets the error.

Q: Why do I only see one device from my multipurpose storage device? The second solution should also work for USBView by the way. The problem is that the device does not exist, the whole directory (/proc/bus/usb) is empty. usb-storage sometimes is overly conservative and sets the value lower than it needs to be.
If you'd like to contribute content, let us know. Go ahead and experiment to find what value works best with your hardware. This is only needed on some models. USB (rev 50) (prog-if 00 [UHCI]) 00:0f.1 USB Controller: VIA Technologies, Inc.
In the example there is only one controller, so its bus is number 1. weblink That device is another hub, and "1-1.3.1" is the device plugged into its port 1. The first one was Intel's "Universal" HCI (UHCI).

I shall say that a message telling "applying debdiff ..." when i was downloading the source called my attention. I just ran across this bug after the earlier midisport-specific bug was marked as a duplicate of this one. The time now is 08:20 PM. navigate here I've marked the apcupsd entries as invalid, and will open a separate bug for the documentation.
Q: My Epson printer doesn't print anything. A: Yes, in two ways. As someone who tries to promote Linux and Open Source, bugs like this really take the rug out from under us and send folk rushing to spend $100s with M$.
With that said, I'm unsure it would make a good Linux based storage platform.
Try reproducing this with the most current stable kernel (and if that doesn't work, then the latest pre-release version) to see if the bug is still "alive". The default value of 240 works well with most devices. The information must be gleaned in another manner. or at least, to kill -HUP the syslog daemon so it rereads its config file.
A: There are two ways to see these messages, which are shown the same way that other kernel debug messages are shown. It seems illogical to require all applications that access USB to be patched for this. You also need to patch this kernel to delay when it tries to open the root file system, as the USB subsystem takes longer than is allowed to initialise and make http://scriptkeeper.net/cannot-open/cannot-open-proc-bus-usb-no-such-file-or-directory-2.html Marking the Hardy task for this ticket as "Won't Fix".
How do I make USB be detected on my machine? Syslog will usually not be able to save the last few messages before an oops or a hang, since it takes time to read the dmesg output and save it. Why is /proc/bus/usb/devices empty? Since these use different HCDs, they may behave differently in some situations.
Q: PCChips M801 with SIS7001 USB Controller provides too little current. A 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 Currently only coldsync works properly with these kinds of devices.

While low-end sniffers might cost only $US400, more functional ones can easily run over $US25K.

The work-arounds presented in this thread do not work because the domount command is also dropped together with all the mount-shell scripts from the initscripts packages.
Q: I'm having trouble using SANE 1.0.3 with my scanner. What am I doing wrong? The devices file itself is created when a usbfs mount is created, using: $ mkdir .usbfs $ sudo mount -n -t usbfs -obusmode=0700,devmode=0600,listmode=0644 usbfs .usbfs $ ls .usbfs 001 002 003 Usbview too.
