Cannot Open /proc/bus/usb/devices No Such File Or Directory

none /proc/bus/usb usbfs devgid=128,devmode=664 0 0 # Reboot. Until the installation of the package it all seemed ok, but if i use qemu alone, my win VM keeps on rebooting. I don't have a /dev/bus/usb/devices file here. Q: What are the sysfs structures for Linux USB? this contact form

I noticed earlier that usbview did not work, but used to under Gutsy. Join Date Jul 2006 Posts 22 It's okay - I found out how to fix it eventually. Join our community today! The location was changed in July as a result of a patch to sysvinit and is now /dev/bus/usb/devices. http://www.linuxquestions.org/questions/linux-software-2/cannot-open-proc-bus-usb-devices-no-such-file-or-directory-378916/

I did know that the wl-520g is supposed to have 2MB only,but I wasn't aware that ASUS is doing the same with wl-500g's. I get "device not accepting address". View all 131 comments or add a comment. You may have to register before you can post: click the register link above to proceed.

When I'd re-aimed kvm at /sys/bus/usb/ I hadn't realised that it looks a for a file 'devices'.

Q: How do I see the "USB Verbose Debug Messages" that I enabled in the kernel config?

The command-line option to use is ts=32k and it is described in the man page for cdrecord. That's a common way for driver bugs to panic kernels, and there are at least three different scenarios to test: driver unused, driver in use but inactive, and driver active. In 2.2 and 2.4 kernels this directory should be created when you load usbcore, however there will be no content till you mount usbfs (the new name for usbdevfs). navigate to this website Bergman (noeljb) wrote on 2009-03-16: #95 apcupsd works without /proc/bus/usb/devices -- documentation error Changed in apcupsd: status: New → Invalid status: New → Invalid 1 comments hidden Loading more comments view

Most USB 1.1 cables work just fine at high speed, but the one you're using might be an exception (maybe it's been damaged). Thus for example, max_sectors = 240 means that a single command will not transfer more than 120 KB of data. both machines are able to navigate the initial selection menus with either a usb or PS/2 keyboard with no problems. Why can't I write to my ZipCD 650 with cdrecord?

So the interfaces show up as; 1-1:1.0 1-1.3:1.0 1-1.3.1:1.0 A hub will never have more than a single interface; that's part of the USB spec. That type of controller doesn't do very much in hardware, which makes the software do more work (and need more memory). I'm not sure who is primary maintainer at Ubuntu - several people are listed as adding patches, and it's a MOTU package. http://ecoflashapps.com/cannot-open/cannot-open-proc-bus-usb-no-such-file-or-directory.html BTW, the noatimemount option should be used to maximize the usb-storage (if flash based) lifetime.

A: This can be one of several problems: High speed devices sometimes have problems with cables used to connect them.

Thank you! A: See the kerneldoc ("make htmldocs" in the root of your kernel), which should be relatively complete in current 2.6 kernels. qemu/kvm reports: qemuctl -qemu vdeq kvm -boot c -m 512 -hda /home/all/VirtualMachines/WindowsXP-SP2.ovl -net nic,vlan=0 -soundhw es1370 -usb -net vde info usbhost Could not open /proc/bus/usb/devices $ ls -l /proc/bus/usb total 0 every variation, all the same result, still getting the error.

usbview may be different (I have not investigated this package). For certain USB mass-storage devices (most notably the USB-IDE adapters made by Genesys Logic) usb-storage automatically sets max_sectors to 64, which corresponds to a maximum transfer length of 32 KB. The information must be gleaned in another manner. his comment is here http://www.open-e.com/products/open-...te/comparison/ Thank you for your quick reply!
