I picked up Two Orico 25PW1-C3 that arrived today
They are Listed as 6Gbps capable in comparison to the 25PW1-U3 that is listed as 5Gbps capable
So presumed they where USB 3.x Gen2
They are JMS576 USB 3.1 Gen1
They only cost £3.50 each so whatever
There doesnt seem to be any firmware around for the JMS576
so here's one
I dumped both devices they have identical firmware and nvram
I have included the flasher that i dumped the firmware with
mega.nz/file/Fi5lQJBL#gFZgo8iQEZ6EUdeVaq...wGkJkkzwP2IzbfTQR_7g

I have a couple of those around, I don't think that bridge was used a lot for some reason, mine were in Blueendless enclosures for 3.5'' SATA drives.
One of the has a firmware that's a bit newer than yours, 01.02.01.04, the other one has some crazy numbering, 250.01.00.03, I wonder what that's about. You can find them both here: mega.nz/folder/EVUyzDwD#GDJCjq149xicZcDER68zfw
I haven't changed anything yet, but the sleep timer is at 0xC4F6 and 0xC4F7 encoded as number of seconds (00 B4 = 3 minutes), but in JMS578 0xC4F2 needed to be changed as well to 30 (I think it was, hex) to disable the timer, setting the other bytes to 0; by the way, none of those firmwares use the details of the connected drive to populate the descriptions (make, model). I remember another adapter I had that used a JMS578 doing it by default if its configuration was cleared (everything set to 0xFF on NVRAM), so perhaps the 576 does as well, but it's probably better to figure out how what to tweak instead thought 😅

Thanks
250.01.00.03 is really old it doesnt recognise the Flash Type as PUYA instead it says unknown
i have seen this type of numbering before some oem's do it for some reason, it will be 01.01.00.03 with 250 added to it..
I tried 01.02.01.04 with your nvram it id's as Jmicron Generic SCSI Disk Device 01.02.01.04
I decided to keep my nvram so it id's as Jmicron Tech SCSI Disk Device and oddly the firmware now id's as 01.05.01.04
all 3 firmware's dont support trim btw
