(New, Pre-production Preview, November 2021) ISOUSB211 - Low emissions, high/full/low speed isolated USB repeater https://www.ti.com/product/ISOUSB211
This is absolutely phenomenal. Texas Instruments just made a galvanic isolation ASIC for 480 Mbps (not 12 Mbps) USB 2.0 that you can actually buy. Finally this problem is solved at last. #electronics #usb
I ordered the pre-production prototype version of TI's high-speed USB isolation chips as soon as I got the news. My order has just shipped today! 
Time to design a development board. #electronics #usb
> isolation barrier capacitance, input to output: 1 pF
wow, that's some serious galvanic isolation. #electronics
Mirror, mirror on the wall, who has the highest breakdown voltage of them all? #electronics #usb
Pre-production preview chips from TI have just arrived. #electronics #usb
1000 volts over USB.
USB Killer ordered, I'm going to unironically use it as a test device on my 1000 volts port isolator... #electronics
BTW, it was claimed that some MacBook models are immune to the USB Killer because the ports have optocouplers but I failed to see any evidence. This is a highly unlikely claim. I wonder what could be the real reason... Pre-enumeration current limiting? CMOS data switch?
Single-chip optocouplers above 100 Mbps for mass markets simply don't exist at all, nearly all vendors use capacitive or RF isolation at higher data rates. And even with an isolator, USB 2.0 HS is bidirectional, you need a controller with state machines to follow the protocol and do bus arbitration, challenging enough that no company ever made such a chip for the open market until Texas Instruments in 2021. #electronics #usb

It's not a bug, it's a undocumented feature!
