Detect When A New Usb-device Is Connected?

Mar 27, 2009

I want to detect when a new usb-device (can be anything) is connected to the computer. I don't need to know what kind of device it is, I just want to know when it is plugged in.

I found this thread: [URL]

I know the solution is in here, but I'm overlooking it I'm afraid. What I want:

WMI Event Watcher - Detect A New USB Device

Mar 7, 2010

I'm trying to detect the insertion of a USB-Serial COM port device. I found an example that shows how to detect a new USB device - and that part is now working well in my project. The question is, how do I pass on that event back to my Form1 class? In the example, I can create a MsgBox just fine, but if I try to manipulate any of the controls on my form, or raise a user-defined event, I get this message: 'System.InvalidOperationException' occurred in System.Windows.Forms.dll

Sep 24, 2009

I am trying to write a VB program to automatically detect and identify a particular device that will only communicate to my program when I have 2 or more devices plug into the USB port. One way of doing it that I can think of is to scan through the available port and do a write and read to identified the port. But that would take up a lot of time if I were to scan through say 5 available port.

Datagridview As An Input Device

Apr 14, 2009

Is it possible to use a datgridview as an input device and then transfer the input to variables (one or two dimensional). I am creating a programme that can be used for a widely divergent number if inputs and the grid would be easier for the user rather than me creating a lot of text boxes at design time which may not be required much of the time and a datagridview would probably be preferable.

Get Custom Data From USB HID Device?

Aug 4, 2010

I've created a custom USB device using a PIC18F4550 and I'm having trouble with reading information from the device. The device sends reports without a request from the application as 64 bytes. I'm relatively new to VB and this is my first foray into USB as well... It's not going good. I've set the Vendor ID to Hex 1234 and the Hardware ID to Hex 0001. I've used different libraries and the timer to check for incoming reports, but I can't seem to figure it out. I've waded through pages of USB Complete and all kinds of code for mice and barcode scanners, but nothing so far that will do anything for my device.. how I can register the device and get the raw report from the device and display it in a text box
