QUESTION
I'm tryng to use an POS printer through WebUSB API with the code below but it fails at .claimInterface()
with an error of DOMException: Unable to claim interface
. All tests are done on Chrome 80.0.3987.116 on Linux. How can I debug this?
(update) I found this demo but it results same error.
...ANSWER
Answered 2020-Apr-03 at 09:24The problem was usblp
driver that was automatically loaded by Linux kernel. Adding it to the blacklist solved the problem. Here's my /etc/modprobe.d/blacklistusblp.conf
file.
