Find the module in the sysfs tree. In this case it was in /sys/bus/usb-serial/drivers/cp2101 In this directory, there is a new_id file entry that can be used to dynamically add VID PID pair like this : echo VID PID >new_id Here is a LWN entry about this feature
Yes, it’s possible, just copy the installation directory to the flash drive, then edit IDEA_HOME\bin\idea.properties file, change the values of idea.config.path and idea.plugins.path to the relative location, like: ../config and ../user-plugins (locations are relative to IDEA bin directory). Now copy your original settings and third-party plug-ins (if any): ${user.home}/.IntelliJIdea10/config => usb:/IDEA_HOME/config ${user.home}/.IntelliJIdea10/config/plugins => usb:/IDEA_HOME/user-plugins Note … Read more
You can do this using udisks. It is not installed by default, but it is easy enough to install (the package is like a megabyte in size once installed)… sudo apt-get install udisks Once installed, you can detach a USB drive with the following commands… sudo udisks –unmount /dev/sdb1 sudo udisks –detach /dev/sdb The first … Read more
You can use the CM_Request_Device_Eject() function as well as some other possibilities. Consult the following projects and articles: DevEject: Straightforward. http://www.withopf.com/tools/deveject/ A useful CodeProject article: http://www.codeproject.com/KB/system/RemoveDriveByLetter.aspx
You can’t simply toggle pins on a USB port. Period. USB is a serial protocol. The connector contains Power. The Host can control the power lines as it can cut the power in case of overload. This is something done by the USB host driver, which means the driver of the host adapter in the … Read more
Answering my own question… I’ve come to realise that this question kind-of misses the point of USB 3.0. Unlike 2.0, it is not a shared-bus system. Instead it uses a point-to-point link between the host and each device (I’m oversimplifying but the gist is true). With USB 2.0, the 125 us polling interval was critical … Read more
Been using usb4java for a year on cross platfom (Linux and Windows) and it works great. See: http://usb4java.org/ They are very active and have a very good javax USB front.
Some USB hubs have the ability to turn power off to its downstream devices. “Is it possible to power up ports on a USB hub from Ubuntu?” https://askubuntu.com/questions/149242/is-it-possible-to-power-up-ports-on-a-usb-hub-from-ubuntu Which points to some c source for hub-ctrl.c See: http://www.gniibe.org/development/ac-power-control-by-USB-hub/index I tested this on Ubuntu with a Dream-Cheeky USB LED unit, and it did seem to turn … Read more
Actually you missed a buzzword “USB sniffing“. 😉 Here are a few tutorials on USB sniffing on Linux, to get you started. Official Wireshark wiki for USB monitoring biot.com/blog/usb-sniffing-on-linux (InternetArchive) tjworld.net/wiki/Linux/Ubuntu/USBmonitoring Essentially you use the usbmon Linux kernel module to capture the USB-packets and Wireshark as a front-end to display and analyse the captured USB … Read more
