Just wondering if we could get some support for the SanDisk Extreme 55AE Portable USB SSD in Linux? Downloadable firmware would be great, but even being able to obtain the information regarding the bridge controller would be a good start. I am currently using Debian 11 (Bullseye) as my OS, and when I tried to get info on the S.M.A.R.T. features of this drive, by running sudo smartctl -a /dev/sda from a terminal, I get this output: /dev/sda: Unknown USB bridge [0x0781:0x55ae (0x3001)].
I’m pretty sure that this is the USB to SSD host controller inside the enclosure, but without opening up the case (therefore voiding my warranty), I cannot identify the chipset that controls this drive. The firmware is unavailable without having a Microsoft Windows or Apple/Mac to run the Dashboard software, and I don’t use either of those OS’es, nor do I have access to either one, so I guess I’m at the mercy of WD/SanDisk to come up with a solution to this problem.
Does anyone (who reads this) know what controller this drive uses? If you have a dead one that SanDisk will not warranty (for whatever reason), if you could possibly (as gently as possible) open the case, and take a (good quality, preferably hi resolution) picture of both sides of the PCB (Printed Circuit Board) of this drive so that I might be able to ID the chipset, and at least provide other developers (and users) with the information necessary to create a solution for this problem?
Many Thanks in Advance!

No need to disassemble your un-warrantied drive! I have found the details of the internals of this drive, and here they are for anyone concerned:
USB Bridge Controller: ASMedia ASM2362 - USB 3.2 Gen 2 to PCIe 3.0 x2 bridge
Disk Controller: Marvell 88SS1074
SSD: WD Blue SN550E M2 NVMe interface 3D NAND SATA SSD
NAND: 64-layer BiCS TLC flash, 16 dies
