[top posting because the information in the original message is somewhat
holographic.]
Thanks for your detailed report. It's hard to help when not enough detail
is included.
Unfortunately, you seem to have perhaps five problems and it is hard to
disentangle them.
- one power failure. Probably nothing you can do anything about.
- "USB over current condition"
How do you know this happened? Is there some indicator?
Is this connected somehow with the NVMe drive?
You seem to have several USB C ports: are all behaving this way?
- reliably powering an NVMe drive, connected via USB C.
What are its specified power requirements?
What can the ports provide?
USB C is a mess: one connector, several standards and options
within those standards, especially with respect to power.
- NVMe disk "lost its type label".
I can guess what you mean, but that would be surprising:
a surgicically precise failure. So much so that it is
unlikely to be the only damage.
Are you using GPT or MBR partitioning?
Is your system booting with "legacy" or UEFI?
- NVMe drive partitions mounting in /var/run
If this isn't where you've told them to mount (via /etc/fstab?)
then perhaps the partions' UUIDs have been damaged.
I would think that the key to getting anywhere is to separately address
each problem. Of course you cannot do that in just any order. I suggest
the order in which I've listed them: each problem should only depend on
the ones above.
Good luck!

| error
|
| I had a power outage a couple of weeks ago which lasted longer than my UPS
| battery life and have had a number of USB issues since then.
|
| While I was separately recharging the UPS, which took about 5 hours, I
| rebooted the system which then immediately froze on boot with an USB over
| current condition. This appeared to be related to the MB front panel
| connection and at first I thought that somehow a surge made it through the
| UPS and had toasted the motherboards own front port connection. This turns
| out not to have been the case. It’s what happened next that puzzles me tho.
|
| I have an external NVME enclosure with a PCI-e X4 512 G M.2 storage which I
| have been tinkering with. After disconnecting the front ports on the MB
| and, I do have a PCI-e 5 port card with 4 x A + 1 Type-C connectors, which
| I had configured to provide four more front ports, with two of them Type-C.
| NB I don’t have the supplemental power connected as I was anticipating only
| to use these ports to use data, for the time being. (This is part of what
| makes me think the voltage demand reporting might be the culprit)
|
| When the front adapter is plugged in this also isolates the Type-C port on
| the actual PCI-e card from being used. After I removed all connections from
| that card and I plugged my M.2 device into the motherboard’s one Type-C
| port the system turned off like a light switch, no hang, just off.
|
| After much fooling around, starting with connecting the keyboard and mouse
| to the onboard legacy USB 2.0 slots, I’m sort of back where I started. The
| two stock USB 3 front ports are connected and working. The supplemental
| front ports are connected to the expansion card and working, sort of,
| Type-A works, Type-C does not.
|
| Connecting the device, if I connect using a cord adapter to Type-A, the
| mounts show up in /run/media. It is configured as a boot device. At first I
| thought the over current was related to the fact that that particular cord
| adapter is 3 ft long, but I’m rethinking that although consistent power
| negotiating and impedance seem to be part of the problem.
|
| What did happen was that the M.2 drive had lost it’s type label and I
| thought I did the right thing by using gdisk to relabel the volume, but now
| it shows up as W95 Ext d (LBA). Also, gparted now shows a libparted error
| for the actual volume I am currently booting from, although gnome-disks is
| fine with it.
|
| Perhaps the libparted error is related to my kernel version and non
| complementary libparted updates. I have seen this as an old issue of out of
| but I cannot so far consistently switch from connecting the device via Type
| A and Type C connections. Maybe this is a memory hangover concerning the
| voltage requested by Type-A vs Type-C

| Unfortunately the cable for connecting the supplementary power to the front
| expansion port was too short so I’m wondering if this is at all related to
| the system registering one voltage demand for the Type-C connection and not
| releasing that info and then re-probing for the increased voltage the SS
| port connection allows for.
|
| Does anyone have any suggestions on how I can unwind some of this?
|
| Perhaps sourcing a longer cable for connecting the expansion cards power to
| the slot might do the trick. I can't say for sure, but I don't recall this
| being an issue before the power issue.
