Title:
USB-Storage Quirk for 174c:1356
Status in linux package in Ubuntu:
Confirmed
Bug description:
A usb-storage quirk is needed for the Mediasonic ProRaid 2 Bay 2.5'
SATA HDD / SSD Enclosure - USB 3.1 Gen-II Type-C (HUR6-SU31) for
reliable use in Ubuntu/Kubuntu 14-17.10. Using quirk 'u' appears to
have fixed disconnect issues during install and use.
Linux Version: Ubuntu 4.13.0-16.19-generic 4.13.4
Device ID:174c:1356 ASMedia Technology Inc.
usb 9-1: new SuperSpeed USB device number 2 using xhci_hcd
usb 9-1: New USB device found, idVendor=174c, idProduct=1356
usb 9-1: New USB device strings: Mfr=2, Product=3, SerialNumber=1
usb 9-1: Product: ASM1352R-Fast
usb 9-1: Manufacturer: ASMT
usb 9-1: SerialNumber: 0000000000000001
usb 9-1: UAS is blacklisted for this device, using usb-storage instead
Note: With/without UAS the issue persisted. I disabled UAS to prevent
devices sleeping to eliminate that as a possibility.
Symptoms: Before using the quirk, the enclosure would completely stop
responding during an install attempt, and the usb host would
eventually be disabled. The device's LEDs would continue to blink as
if being accessed.
Fix: I specified the quirk by appending "usb-
storage.quirks=174c:1356:u" to the linux line in Grub. Hopefully
others can verify this (if I'm not insane) and include a patch for
this upstream in the Kernel.
Note: For those who install to a device such as this, you may need to
modify your installation before booting it, by creating a file
"/etc/modprobe.d/asm1352r-usb-quirk.conf" with contents "options usb-
storage quirks=0x174c:0x1356:u". I have seen others (through Google)
issuing the same "u" quirk for several ASMedia devices...Perhaps their
chipsets need this?
This is my first bug report. If any more information is needed, please
inform me. I'd like to thank a TJ- in Ubuntu's IRC for helping nail
this down.
