The slow USB transfert issue is encountered by every Iron's owner. OTG connections and PC connections are not using the same "software" parts and it's why Otg works fine.
Could you try in TWRP recovery whether you experience the same slow data transfer or not? Just don't forget to mount the internal storage and enable MTP.
Thank you for the detailed description of your ...
The port is definitely USB 2.0 as i use it all the time for (much) faster transfers to a USB stick.
I'm using the same cable that i have (and am using) on different phones (e.g. the girlfriends Galaxy S4) to transfer files.
There doesn't seem to be any issue with the PC, as USB 2.0 is working from all ports as normal. Why would the Iron be working on (presumably) USB 1.0 speeds?
Has anybody got any suggestions for wi-fi file transfer solutions in the meantime? I used Kies in the past on my old Galaxy S2 which was pretty good (although not as user friendly as just file browsing through USB connection)
Edited by Kretek at 2015-9-28 22:20 \n\nTry WiFi File transfer (pro) from the market. It faster than USB cable at the moment.
EDIT: Using TWRP I get same speeds (1,3 Mb/s) over usb cable.

Then that's a kernel based issue or just a hardware defection of some devices. I still don't see that proven, all Irons are affected by this issue.
WiFi File Transfer is a good idea. That even can be faster than a high speed MTP connection if you copy a lot of tiny files, not a few big ones.
How can you prove this?
There was a previous thread about this issue (where your post has been removed, just checked it out) and no one says that the issue isn't affect him.

I just couldn't find this issue netwild reported by other users or testers, reviewers etc. On forum.xda-developers.com I just saw the same few people discussing about this as here. I don't dispute that's a general issue, just can't see it proven.
I also think it is a General problem on all umi irons.... Very slow usb speed. Also usb mode is not detected by PC. Only MTP. The flash is useless also because it fires too late. UMI Take the buyers seriously because you know you have too many competition. I think this are all bugs with possible correction. Give us ROM 1.7.
Yes, that has been discovered already. Developers are working on to solve both issues, the slow USB and the flash delay. For USB data transfer, mass storage mode won't be available due to the restriction of Android 4.4 and above systems. As a better solution for USB file transfer, a recommend to use Total Commander with MTP plugin.
bencebacsi is there any schedule for next update? Could you please ask UMI about:
- plans for implementing camera2 api
- introducing other roms (CM, MIUI) - right now we have only Flyme (not all of the features work) and I'm talking about real alternative
- what are the plans regarding Marshmallow?
