Hello,
I am testing TUSB9261 evaluation board, using the v1.00 firmware.
The board works properly with a 60 GB Intel SSD, and with a Soligen 256 GB SSD, but fails with two different Intel 256 GB SSDs.
The Intel SSDs which don't work with the TUSB9261 do work in a desktop Linux machine which has an mSATA slot on the motherboard.
All Intel SSDs tested are mSATA SSDs from Intels 525 series.
I'm not using Superspeed USB, just regular 2.0.
On the desktop Linux machine, I get the following errors with the Intel 256 GB disk in combination with the TUSB9261:

... and the errors continue
I think I may get different errors at different times. Once I actually got the drive to mount properly.
I'd appreciate any advice on what to do.
It definitely seems like it's the combination of the TUSB9261 and the Intel 256 GB drives that are the problem.
Strangely the 256 GB Intel SSDs have a blue solder mask, while the 60 GB drive has a green solder mask.
