Hi, I'm running kernel 6.1.43 and I'm running into an issue with a JMS578/JMS579 USB-SATA adapter connected to an SSD. When I first connect the adapter to the USB port of my laptop, TRIM support seems to be disabled: $ lsblk -D | head -n 2 NAME DISC-ALN DISC-GRAN DISC-MAX DISC-ZERO sda 0 4K 0B 0 (Notice the DISC-MAX value). However, if immediately after that, I remove and insert the uas module, then TRIM support seems to work fine: $ modprobe -r uas $ modprobe uas $ lsblk -D | head -n 2 NAME DISC-ALN DISC-GRAN DISC-MAX DISC-ZERO sda 0 4K 4G 0 This seems to happen very consistently (both the disabled TRIM when first connecting the device and the enabled TRIM when reloading the module). As far as I know I don't have any udev rules for this device, but I don't know how to verify this for sure. Any ideas of what could be wrong? Thank you.
