Access USB from Qt???

[webquinty]

Hello,

I am surfing in the net looking for information about Qt and how to access USB port.
I only find messages about libusb.
My question is:
has Qt native support to acces USB port or is it necessary to use libusb into Qt to access USB device??

Best regards
John Martin

Hi, unfortunately there is no native Qt USB port handling support.

It depends on the reason why you want to access USB port. If you want to access a device which simulates a serial port for example, then there are such third party classes available.

AFAIK you will have to implement libusb directly. Its not much of a pain. Although if you have used the .net wrapper for libusb you may perhaps miss it. There is nothing like a qt wrapper for libusb. And yeah, it works :)...

We had lots of fun working with libusb and also SliLabs usbxpress in GoldenCheetah. There is some example code in LibUsb.cpp and USBXpress.cpp over at github. See: https://github.com/srhea/GoldenCheetah/tree/release_3.0.0dev/src

Best regards.
