MSDN says that there’s a generic USB device interface class named GUID_DEVINTERFACE_USB_DEVICE with the GUID {A5DCBF10-6530-11D2-901F-00C04FB951ED}: The system-supplied USB hub driver registers instances of GUID_DEVINTERFACE_USB_DEVICE to notify the system and applications of the presence of USB devices that are attached to a USB hub. Here’s a code example that seems to do what you want … Read more
Create a dummy window that does nothing but wait for WM_DEVICECHANGE and register that window using RegisterDeviceNotification. WMI is an overkill here, IMHO.
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.
Try: gwmi win32_diskdrive | ?{$_.interfacetype -eq “USB”} | %{gwmi -Query “ASSOCIATORS OF {Win32_DiskDrive.DeviceID=`”$($_.DeviceID.replace(‘\’,’\\’))`”} WHERE AssocClass = Win32_DiskDriveToDiskPartition”} | %{gwmi -Query “ASSOCIATORS OF {Win32_DiskPartition.DeviceID=`”$($_.DeviceID)`”} WHERE AssocClass = Win32_LogicalDiskToPartition”} | %{$_.deviceid} Tested with one and more than one USB device plugged-in.
I was trying to send data over the wrong baud rate. Here’s the code that works. Posting it for everyone who is using FTDI devices and needs help. private Runnable mLoop = new Runnable() { @Override public void run() { UsbDevice dev = sDevice; if (dev == null) return; UsbManager usbm = (UsbManager) getSystemService(USB_SERVICE); UsbDeviceConnection … Read more

In my case this was Windows 7 I got a little hint from This page on eHow; not sure if that might help … Read more
Update: As said in comments, Hal is not supported in recent distributions, the standard now is udev, Here is a small example that makes use of glib loop and udev, I keep the Hal version for historical reasons. This is basically the example in the pyudev documentation, adapted to work with older versions, and with … Read more
The world has changed since this question was asked, and the answer is now the Android Open Accessory Development Kit. It won’t solve the problem for existing USB devices, but it makes it possible to create new devices that can use an Android device’s USB connection.
It is not a adb-connection-by-wifi what gets killed. It is just that USB enumerations affect the sys.usb.* system properties which on many devices is causing restart of adbd regardless whether it’s being used over USB or tcpip. Do grep “stop adbd” /init*rc to see what I mean. You could either comment out those stop adbd … Read more
