Hi Zoltán, A while ago you submitted a patch for libusb to fix issues with a libusb based app for your weatherstation: http://libusbx.1081486.n5.nabble.com/Libusbx-devel-libusb-interrupt-transfer-does-not-return-in-case-of-error-td626.html
This resulted in this patch being added to libusb: https://github.com/libusbx/libusbx/commit/2f5023c41d3176e56bf0abc521b7c5f8b1ac4664 I encountered this patch while working on some other libusb stuff, and I believe it is wrong, it may make things work, but it is masking the real problem. In your original mail you gave this bit of libusb output logging: [372849.680990] [0000275b] libusbx: error [reap_for_handle] reap failed error -1 errno=14 [372849.681752] [0000275b] libusbx: error [handle_events] backend handle_events failed with error -1 [372850.680466] [0000275b] libusbx: warning [handle_timeout] async cancel failed -5 errno=22 The problem begins with reap_for_handle failing with errno == 14, which is EFAULT. So the real problem is the weather station application you're using passing in an invalid (or too short) buffer, and thus is an application bug (or so I believe). If you can send us (a link to) the sources for the weather station app, I can take a quick look if I can spot the problem. Note this issue is being tracked here: https://github.com/libusbx/libusbx/issues/76 You can either reply directly in the bug-tracker, or simply reply to this mail and then I'll keep the tracker updated.
