Did you try looking at the source code for the existing USB drivers??? Do you know how to program?? Your previous threads don't indicate much of a background.

Look at the existing source code, which you should easily be able to download from the Red Hat site, if you're still using RHEL 7 (after being told repeatedly not to).

Start from a web-search of:

allintitle: write linux usb driver

Also try LQ's Advanced search, choosing: Search Titles Only, Show Results as Threads, for:

Quote:

writ* usb driver

You should find several; do you see them? (note: on LQ, that * matches {e,ing,ten} )

After reading thru the results for at least a fraction of an hour, post your choice of best 2.

Please post that device's info from: lsusb

Tell us a bit more about your: distro, experience, any other necessary details.

Thank you. Best wishes in this project. Awaiting your reply.

I suggest that you start with the O'Reilly book on writing Linux device drivers.
