    <p>How can we query connected USB devices info in Python? I want to get UID Device Name (ex: SonyEricsson W660), path to device (ex: /dev/ttyACM0)</p> <p>And also what would be the best Parameter out of above info to be used as identifying the device whenever it's connected again? (UID?)</p> <p>I am working on Ubuntu 11.04.</p> <p>ATM I have this code (using pyUSB)</p> <pre><code>busses = usb.busses() for bus in busses: devices = bus.devices for dev in devices: print repr(dev) print "Device:", dev.filename print " idVendor: %d (0x%04x)" % (dev.idVendor, dev.idVendor) print " idProduct: %d (0x%04x)" % (dev.idProduct, dev.idProduct) print "Manufacturer:", dev.iManufacturer print "Serial:", dev.iSerialNumber print "Product:", dev.iProduct </code></pre> <p>The problem is I don't get desired output, will paste one example:</p> <pre><code>&lt;usb.legacy.Device object at 0x1653990&gt; Device: idVendor: 4046 (0x0fce) idProduct: 53411 (0xd0a3) Manufacturer: 1 Serial: 3 Product: 2 </code></pre> <p>First I don't get filename, it's most important to me. I am assuming it is the /dev/ttyACM0 etc part. Second, I guess there was some UID of every USB device, or I should use both Vendor or Product id?</p> <p><strong>EDIT: Apparently I have some setup issues, I think I am using wrong USB Library. (using libusb0.1) ATM. That's why I get Device (dev.filename) string empty. If someone can please just tell that on what operating system he is using what USB Library and what version of PyUSB I think it will solve my problems.</strong></p>

Querying!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
