Some external references are available here and here. Learning that two kinds of register interface was one too many, USB 2.0 defined just one, with much less legal encumbrance. 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 Comments please? http://www.linuxquestions.org/questions/linux-software-2/cannot-open-proc-bus-usb-devices-no-such-file-or-directory-378916/
Re-opening the sysvinit task: I'm not affected by it myself, but I wonder why we cannot just enable the magic to make it work by default, from /etc/init.d/mountdevsubfs.sh (code commented out A: There are many changes to the SCSI subsystem in 2.4 which means the back-port is unlikely to fully functional. A: A user reported this.
Configure all your kernel USB facilities as modular, including support for both UHCI and OHCI host controllers (unless you're positive you know which type you have), and enable HOTPLUG. Q: What APIs are available to USB Device Drivers? A: You can either manually configure /etc/conf.modules (or /etc/modules.conf with 2.4-ready versions of modutils) to load the modules you require like this; alias usb uhci post-install uhci modprobe printer post-install printer Use an external high speed hub.
The alternative is to add a complete new set of scripts and links, either: /etc/rc.S/S12mountdevusbfs -> /etc/init.d/mountdevusbfs.sh or /etc/rc2.d/S20mountdevusbfs -> /etc/init.d/mountdevusbfs.sh That, coupled with the alteration to KVM/QEMU would solve the Q: My Asus motherboard doesn't work, or works with only one device A: Some early Asus P2B-DS and P2B-D motherboards have a design flaw that means that the chipset doesn't get usbview may be different (I have not investigated this package). https://ubuntuforums.org/showthread.php?t=849495 Join our community today!

That type of controller doesn't do very much in hardware, which makes the software do more work (and need more memory). General Wikidot.com documentation and help section.
This solution also worked on the Gateway 2000 Solo 5150 notebook. A: One basic thing is to make sure you make sure there are no dependencies on particular host controller hardware or drivers. We don't have to care about kernel backwards-compatibility :). Specific Hardware Problems Q: How do I make USB work on my Sony Vaio laptop?
This is the result: mount -t usbdevfs none /proc/bus/usb mount: mount point /proc/bus/usb does not exist mkdir /proc/bus/usb mkdir: cannot create directory `/proc/bus/usb': No such file or directory And supposed I weblink These HASP keys will still be around for the next 10 years.

Anyone? TJ (tj) wrote on 2007-10-27: #4 Your initial comment made me smile - it was the first thing I tried. According to their technical support staff transfers should be limited to 32 KB (max_sectors = 64), and usb-storage automatically sets max_sectors to this value when it detects a Genesys Logic device. navigate here By the way, I see that vmware-server is mentioned here.
Christopher Blay (blayde) wrote on 2007-10-27: #3 alright, i take back my previous comment (i learned something new today). Sorry for sitting on this task so long. The second solution should also work for USBView by the way.
It seems some devices do not like this new method though.
Seems like there's been a long trail on this one. Remember, always say what kernel version you're using including summarizing any custom patches you're running. If you are using Linux 2.4, don't expect community assistance unless you first upgrade to a recent 2.6 kernel. Then, if your Linux distribution for some reason hasn't included hotplug support, you can get the hotplug scripts release over at the linux-hotplug project and install it using the instructions there.

View wiki source for this page without editing. Many devices have limits on the amount of data they can transfer, and if you try to exceed that limit you will most likely crash the device. A: For example the directory will have something like: # ls /sys/bus/usb/devices/ 1-0:1.0 1-1.3 1-1.3.1:1.0 1-1:1.0 1-1 1-1.3.1 1-1.3:1.0 usb1 The names that begin with "usb" refer to USB controllers.

A: You could ask on the Linux USB User/Help mailing list.
The information must be gleaned in another manner. A: If you've setup the hotplug scripts it should be there, please report this to the user's mailing list. The reason might be a device drivers assuming some HCD-specific behavior, or an HCD not doing the right thing. Powered by vBulletin Version 4.2.2Copyright ©2000 - 2016, Jelsoft Enterprises Ltd.
