Summary0013028: Sync: Multiple USB Thumb Drives of same type get same profile
DescriptionSometimes when multiple USB drives of same type and size connected one by one get recognized under same Profile.

Workaround is to connect all drives simultaneously where Windows assign different IDs to them and MMW then detect them differently and create separate profiles. Afterwards each thumb drive is correctly detected even connected one by one.

Exported profiles of all drives are uploaded to FTP for comparison.

Peke, I guess that in the last 4.1.10 builds (due to change 0012997:0043512) this cannot happen anymore supposing that each of the profile was at least once synced with MMW and the storageInfo.xml was created, can you please confirm?

If yes, then I would suggest just close the issue.

I deleted old profiles. There was bunch of duplicate profiles so we connected all 4 drives at once to see which one is which.

Most likely you are right, last night in remote session I upgraded him from 1758 to 1776 and then saved all 4 MMDS, before upgrade there was 8-10 profiles with same ID and different names.

Should we create KB article to cover this?

eg. if multiple drives of same Model, size are recognized as only one profile we should suggest that user delete existing profiles and create new which will detect each one as separate device?

I don't think there is a need for KB article, once the profile is at least one synced then storageInfo.xml is created and such a profile will never be used for another storage (even if inserted to the same SD card slot).
So for another SD card in the same slot another profile will be created.

i.e. marked as resolved in (related to 0012997:0043512 fix )

They are not SD cards but USB flash drives it is opposite case of 0012997:0043512 where multiple USBs connected to same PC prior to any sync DONE, so no storageinfo.xml

Are you sure that this also apply in this case?

1. Connect USB stick
2. Set profile in MMW (No Sunc)
3. Disconnect Stick
4. Connect second Stick (same model and size)
5. MMW recognize it like it was first stick

If you skip step 3 than in step 5 you will have two profiles and from now on if you repeat original steps 1-5 MMW detect sticks correctly

I saw the MMDCs of the sticks on the FTP and see that all the profiles has slightly different DeviceID so I think that starting from build 1776 this issue doesn't happen anymore with the sticks. (prior to build 1776 the IDs were compared also based on similarity which could result in 0012997)

Another issue is if MMW cannot distinguish between the storages at all (like 0012205) then all storages are getting a single profile until a storage is synced and gets assigned own storageInfo.xml and thus own profile ( 0012820)

Thank you for clearing this out, 1776+ is working for user too.

Closing think we covered all angles.
