#1817 New Device: Nox A1 medical device

[Anonymous]

New device that libmtp 1.1.15 is unable to recognize. This device is manufactured by Nox Medical, located in Iceland. It is used to capture patient signals during sleep.

mtp-detect returns:
libmtp version: 1.1.15

Listing raw device(s)
Device 0 (VID=1e0a and PID=1001) is UNKNOWN in libmtp v1.1.15.
Please report this VID/PID and the device model to the libmtp development team

is it really a MTP device?
what is lsusb -v output?
does mtp-detect work as root?

see my post below.
mtp-detect works as root.

Hi Marcus, sorry for the late response.
This is indeed an MTP device. I have already implemented C++ code that works on Windows platform to communicate with the device.

There is no lsusb command on Mac, but I installed a wrapper around profiler command to get similar results. lsusb -v outputs:

this mtp-detect output is showing failure ... :/

but I will add the ID to git

Hi,
I started to have similar issue some time ago in Debian Buster (Sid):

$ sudo mtp-detect
libmtp version: 1.1.16

Listing raw device(s)
Device 0 (VID=2a47 and PID=2008) is a bq Krillin (MTP).
   Found 1 device(s):

I can't browse my Ubuntu Touch-based smartphone. And had issues woth some older Huawey Android too.

I don't see any "mtp-related" messages in syslog after I connect device:
