Next time you are infront of the computer, copy paste this information please from both direct plugged to usb and via hub. Believe you do in the church, not infront of the computer, when we see the output we can conclude ourself. regards
Re: MTP device mount gnome 3
I am not at computer right now, sorry, but I checked dmesg while the phone was plugged to the hub, and dmesg has shown manufacturer of device, so I believe device is detected properly, it's just MTP that does not work. 23 янв. 2017 г. 1:05 AM пользователь "deloptes"написал: > Vadim Kolchev wrote: > > > The phone charges, it is just that it does not mount.

Re: MTP device mount gnome 3
The phone charges, it is just that it does not mount. I can even reach it with adb and push and pull files 23 янв. 2017 г. 12:47 AM пользователь "deloptes"написал: > Vadim Kolchev wrote: > > > Basically it is not an option for me, because I need to use this USB hub, > > it is an external audio USB Interface that gives rather high quality > audio > > to me, and it has 3 USB ports.

Re: MTP device mount gnome 3
Basically it is not an option for me, because I need to use this USB hub, it is an external audio USB Interface that gives rather high quality audio to me, and it has 3 USB ports. Not interested in any other USB hubs. Seems like I will connect my phone directly to USB in motherboard. 22 янв. 2017 г. 7:14 PM пользователь "deloptes"написал: > Vadim Kolchev wrote: > > > What exactly is meant by a "better hub"?

Have you tried with different hub? My experience shows that there are hubs of a better and hubs of a lower quality. With some hubs something may work with some other may not. I experienced a similar problem with usb dvbt stick and I don't know what was the root cause exactly - if power too low or something with the hub. regards
Re: MTP device mount gnome 3
Yes, Frederic, My Hub is self-powered, Cable for smartphone looks ok, as long as I use the same one to connect to PC USB directly and it works. Seems like HUB is unable to work with MTP device. Also, I cannot try to connect smartphone with HUB cable becaue they are totally incompatible. 2017-01-22 16:05 GMT+02:00 Frédéric Marchal < frederic.marc...@wowtechnology.com>: > On Saturday 21 January 2017 07:47:25 Vadim Kolchev wrote: > > Hello, > > Just noticed an interesting thing > > Have an MTP Xiaomi smartphone device, all relevant packages installed. > > Also have M-Audio M-track HUB external soundcard with 3 USB ports. > > > > When connecting MTP device to HUB, have message in dmesg about Xiaomi, > but > > it does not mount and cannot be accessed. > > > > When connecting to USB port of the machine directly, it shows in > Nautilus. > > > > I really got used to HUB, is there a way to fix it? > > My experience with MTP and a Samsung smartphone is that the usb cable > gauge is > critical. > > A standard gauge 28 cable is too thin to provide a good power supply to the > phone.

My experience with MTP and a Samsung smartphone is that the usb cable gauge is critical. A standard gauge 28 cable is too thin to provide a good power supply to the phone. The device constantly disconnects until Android gives up claiming that it could not find a suitable program on the host computer to communicate with. I tried gauge 24/28 cables. They give a somewhat better result but it is far from perfect. I suspect the cable is not entirely to blame at this point. Your hub or its cable could be unable to provide the required power supply to the smartphone. Is your hub self powered? Have you tried to connect the smartphone with the hub cable? It may be too thin for MTP requirements. Frederic

Or having to disable access to the block device from one OS, which can really mess up applications trying to access it. What happens on your computer if you are running an application where the binary itself or the data it needs is on a USB device and you pull the device out? Now imagine that describing everything you're running. > I've given up on getting it to work consistently and have installed dropbox > on my phone and desktop to move stuff back and forth, which also has its > headaches and limitations, but is consistent, and works.. That's essentially what MTP does (only without using an third location to sync against). Well, probably closer to using FTP to files to/from the device, only without using TCP/IP. (Oh, just refreshing and apparently one can run MTP over TCP/IP, though I suspect that implementations being talked about here are still direct USB connections.) Any fancy GUI for navigating file systems should function as well for an MTP attached device as it would for say, an FTP service. >From what I've heard, MS had 3rd tier engineers develop MTP, and even they are a little ashamed of it. But, it's still the primary protocol out there. So, the idea of MTP is sound, but the particular design, and the various implementations, well... there is probably room for improvement. But it's unlikely to happen with anything less than full industry support. mrc
Re: MTP device mount gnome 3
My experience has been that this whole "MTP" thing, instead of just mounting phones like they used to, as a storage device, has been a real horror show, I've given up on getting it to work consistently and have installed dropbox on my phone and desktop to move stuff back and forth, which also has its headaches and limitations, but is consistent, and works.. for a while I was just using an ftp client, ANDFTP, to move stuff back and forth to a directory on my rented VPS in Germany that I had sshfs mounted here at home, which also worked, but was a little more klunky, as they say (bit of a kludge?)

Re: MTP device mount gnome 3
What exactly is meant by a "better hub"? It works ok with all types of USB flash drives, which are detected properly. It is only MTP device that is not detected. 2017-01-21 20:57 GMT+02:00 deloptes: > Vadim Kolchev wrote: > > > I really got used to HUB, is there a way to fix it? > > get a better hub? > >
