Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.15 kernel[0].
If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.

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.
