I bought a Velleman VTLAN7 cable tester.
For testing cables USB it has only a socket USB Mini-B as master to socket USB Type A as remote.
Unfortunately this limits the scope/use of this tester to only a few cables, but there a lot more cables with other plugs and receptacles to test.
Ho to do this with this VTLAN7 cable tester? Is there an extension/enhancment available to this tester allowing to test other kinds/combinations of USB cables?
But in the description https://www.velleman.eu/products/view/?id=410544
there is said:
“eignet sich zum Laden, nicht zum Synchronisieren”!
So may be there are not all wires/leads in the adapter. Only those for power, but not for data.
You are absolutely right, the adapter is only for power lines, not data lines.
At this time, Velleman does not have adapters available with all 4 lines connected.
