Subj : USB 3 Issue? To : Ky Moffet From : Barry Martin Date : Fri Dec 13 2019 07:46:00 Hi Ky! > KM> Musta misread; thought you'd said the DVD was causing the issue. > Could have been a misread (like I've never done that!!), poor phrasing > on my part..... KM> Poor or missing parts. Cheap components. Defective design. Damn, KM> I want a whole new monkey. :D OK, so could be any one thing, could be a combination of things (one add-on card 'radiating' into the motherboard; multiple cheats all over adding up). Looks like one of those "just need to put up with it" quirks. > Doesn't seem to be a stall; not sure the last time I let things sit but > shouldn't take too long as I generally use 16 GB thumbdrives.

Keep an eye out for common denominators - right now seems to be the motherboard and power supply. And the OS. > LIS most of the time the thumbdrives play nice -- most are USB 3's and > generally plug them into the added-on USB 3 port on the front panel.

Might be affected KM> by some issue in the mainboard's own USB, which only about half KM> works. Southbridge bug, maybe. (Was gifted two of the same board, KM> and one was marked "bad southbridge" tho now that one seems to KM> work. Maybe both of 'em...) The motherboards looked around, saw the one you put on the fence and shot, decided they'd try to work to avoid that fate! Here the USB 2 front panel is integrated into the case but still an add-on. USB 3 front panel is a 3«" bay insert. So both front panels add-ons. ...Semi-deciphering 'lsusb -t' -- right now nothing in the front so so far just a listing; don't want to insert and have a lock-up in the middle of this reply! Have a powered USB 3.0 hub; swapped that out a little while ago because it seemed to be wonky. Went from a four port to seven, different brand (though chip could be the same); same issue. Left the seven port in as I like the additional ports. > Yesterday plugged in headphones and that locked up the system (!) -- > that port is part of the USB 2 panel built in to the chassis. (Still an > add-on.) Think I tapped for static discharge -- usually do in winter > but can't be 100% sure. KM> USB self-grounds before the powered part makes contact, so KM> shouldn't be an issue. Tho note that headphones would have been a KM> sudden power draw. Possibly poor phrasing on my part: the headphones were just audio - the 3.5mm round, not USB. KM> You might want to get one of those little blue pass-through USB KM> testers that show voltage and draw, and check if there's a sudden KM> power drop, or worse, a spike. Also I would look at voltage on KM> the system power supply -- I have a tester that displays it for KM> each rail, but voltage reads might be in your BIOS under "PC KM> Health" or something like; maybe try hotplugging the offending KM> USB device and see if voltage jumps. If the 5v is out of whack, KM> that would affect some USB devices. OK - have a USB voltage tester. I think the BIOS does have voltage readings but haven't paid too much attention so will check. KM> === KM> Only at Ky's House: only reason I've had the linux box up in the KM> last month was to run updates. And then run updates on its baby KM> brother in the VM. This is silly. :P Tweedee and Tweedledum?! I haven't used the VM Linux all that much and have forgotten it will need updating. ¯ ® ¯ Barry_Martin_3@ ® ¯ @Q.COM ® ¯ ® .... Q.
