I think you can use UDEV to do what you want. Creating a rules file such as/etc/udev/rules.d/99-thumbdrives.rules you'd simply add a rule that will allow either a Unix group or user access to arbitrary USB thumb drives. KERNEL=="sd*", SUBSYSTEM=="block", ENV{DEVTYPE}=="disk", OWNER="<user>", GROUP="<group>", MODE="0660" Would create the device ...

Boot with: quiet loglevel=3 For info: quiet [KNL] Disable most log messages loglevel= All Kernel Messages with a loglevel smaller than the console loglevel will be printed to the console. It can also be changed with klogd or other programs. The loglevels are defined as follows: 0 (KERN_EMERG) system is ...

USB 2.0 or 3.0 is a hardware specification and has little to do with the OS. There's no way to downgrade (or upgrade) an specific USB version. What you can do is plugging your device in a 2.0 hub. USB 3.0 is totally backwards compatible with 2.0 and 1.1 devices, but some glichs can appear in the kernel implementation of the specification, in such cases is ...

If Miroslav Koskar's suggestion regarding kernel loglevel did not help (you might as well use 2 or 1 there instead of 3, IMO), have a look in your /etc/syslog.conf (or rsyslog.conf) for a line containing /dev/console. This indicates the level of messages that are passed to the console by the system logger, which maybe the case if the kernel isn't doing it ...

Magic numbers (or in this case, identifiers) are most of the time random, through sometimes funny (think hexadecimal DEADBEEF). These numbers could or couldn't be incidental, but there's no reason why they would want to be "close anagram" of anything. I would brush off as mere coincidence.

USB is dissymmetric: one side is a host, the other side is a peripheral device. You can't make a peripheral device act as a host or vice versa. It is possible for a USB port to be able to act as either side; this is called USB on-the-go and is present on some mobile phones and tablets. The ports are physically device-type ports, not host-type ports. I've ...

The devices in /dev/bus/usb/XXX/YYY follow naming policies in the kernel as noted Gilles in the comments. XXX is the bus number which is quite stable, but YYY changes every time the USB device gets enumerated (when a device just got inserted or reset). This cannot be changed and you shouldn't have to change this either. If you need to change permissions on ...
