Description
In windows device manager under Universal Serial Bus device I see attached printer with name of 'Virtual Com Port' escpos is unable to communicate to with it. I've tried by providing `VID` and `PID` while defining usb device but doesn't work. `escpos.USB.findPrinter() ` doesn't find anything as well.
More over I've tried defining a serial port with device path but still no luck.
Any Suggestions ?

Start by reproducing the Windows Device Manager setup for the printer shown as “Virtual Com Port,” then inspect escpos.USB.findPrinter() and the serial-port device-path configuration described in the report. Done means determining whether this device can communicate through the existing USB or serial paths and documenting a verified outcome.
