Re: USB m.2 SSD adapter interferes with m.2 drive on mobo

This is before my PC even boots into the OS. The issue is that when that USB drive is plugged in when my PC boots up, the boot drive (which is one of the m.2 SSDs) appears as no longer available, so it can't boot into the OS.

Yes... I realized after I left the reply that it wasn't applicable to your issue... sorry about that.

I guess I was just in a 'shit all over Win11' mood...

While I haven't had specifically the same issue, I have indeed had plenty of various issues when leaving USB things connected and rebooting. In general, USB is absolute garbage. It's barely fine for HID (keyboard, mouse, etc). It's definitely improved over the years, but improved garbage is still just that. USB-C is almost getting there, adding a lot of features but I dunno if it's improved in leaps and bounds in stability/reliability. Anyway, my suggestion is not to expect USB drives and other complex devices not to goober your USB things on reboot. Janky busses, janky OSes, janky drivers.. not a great combination. Unplug, reboot, replug. On unexpected reboot, pray.

reviews that suggest disabling usb booting.

my guess is your motherboard thinks it's 'helping' by disguising your usb

Good call.

Considering that USB has been around for a long time now, I'd think it would be better.

Isn't USB-C just a different type of connector for USB? You can buy adapters to plug USB-C into USB-A and vice versa (and same with USB-C to micro USB). I'm unclear on what you mean by USB-C adding features.

That's a bummer. I've actually never had this problem before with a USB device, but I think this is the first time I've tried leaving a USB storage drive attached to my PC.

Yes, but it's also more bandwidth and has all kinds of fancy new negotiation. Like all the different power options that can go through it, etc. It's not just 4 pins (5v, Rx, Tx, Gnd) anymore. Not sure how much the code/drivers for the USB busses has changed to accomodate for the newly expected uses and fuctionality.

But yeah, most of the time you leave the drive plugged it, it should be fine. In my experience, though, it's not unheard of for it to either not show up or muck up the drive order or some other such weirdness on reboot.

depending on how those are wired up it kind of looks like you'd either end up with USB 2.0 speeds, no USB-PD support, no video output, or some other combination of limitations. you're dumping a 24pin connector down to 4 after all
