[Cialug] OT: USB Issues

Tue Jun 14 02:44:54 UTC 2022

While it is not for sure, it is VERY often the case that the psu absorbs

Even though the motherboard and things are often more delicate, it always
seems to affect the PSU more than you would expect.  Sometimes it makes it
marginal, sometimes it kills it outright.
