Good morning,
I am working with the Conduit mLinux version and I have a problem with the binary that provide me the Loriot cloud service. It is not working correctly. The issue is that when I run it, eliminating the LoRa server and the packet forwarder of Multitech first, the USB driver logs errors, and most of the frames sent by the mDot are lost. Only a few ones reach to the server in the cloud, and all others are not detected by the Conduit’s Loriot application because are lost in the USB FTDI. The Loriot’s support said me that they have tested the binary with the Conduit AEP version and it runs OK. But with the mLinux version the behaviour is erroneous. The error in the log is: mtcdt user.debug kernel: usb 1-2.2: usbfs: usb_submit_urb returned -121.
When I run the binary with strace, the trace errors are those repeating all the time:
clock_gettime(CLOCK_MONOTONIC, {315, 221587000}) = 0
ioctl(8, USBDEVFS_SUBMITURB, 0x638a0) = 0
timerfd_settime(7, TFD_TIMER_ABSTIME, {it_interval={0, 0}, it_value={435, 221587000}}, NULL) = 0
poll([{fd=5, events=POLLIN}, {fd=7, events=POLLIN}, {fd=8, events=POLLOUT}], 3, 60000) = 1 ([{fd=8, revents=POLLOUT}])
ioctl(8, USBDEVFS_REAPURBNDELAY, 0xbeb8a984) = 0
timerfd_settime(7, 0, {it_interval={0, 0}, it_value={0, 0}}, NULL) = 0

Any idea on how to resolve this issue?
Thank you and regards,
