Comment 20 for bug 1886172

I have tested it

1) directly connected to two different computers

and and with

2) a external hub with both these computers.

All works in 4.15, but not now. The external hub has an extra power supply and can give up to 4 A for the charging only port. Hopefully it is limited to 2 A per port by design for normal use.

The drive's enclosure itself is designed for 2 A, i.e. single connector.

High speed requires more power, but the speed can be that for 45 to 60 minutes. I expect it fail earlier if it is short of power, in case you use the dd-command.
