Misc¶
Misc subtab
The Misc subtab contains Cable information, Send request, and Overrides
Cable information¶
Cable information panel with e-mark data
Displays power and data capacity for e-marked cables connected to the hub and a device.
Hub port must be providing VConn (VConn strip chart showing 5 V)
If VConn strip chart shows 0 V, send “VConn Swap” message to swap whether the hub or device is providing VConn
To read e-mark without a device, connect both ends of the cable to ports of USBHub3c, with one port set as sink or auto and the other set to source or auto. View the cable info panel on the source port.
Send Request¶
This control sends USB PD requests to the connected device to initiate a connection sequence. There is no guarantee that the request will succeed, and many of these request messages will be unsupported by the connected device.

Overrides¶
Cable current – overrides the 3 A current limit for cables that don’t specify 5 A via e-mark
Port power limit – overrides port power budgeting and allows full power output up to 105 W per port
Warning
Can exceed power supply current limit and brown out the hub, triggering a reset
Auto discovery – overrides the auto discovery feature. When enabled, the hub will only establish a basic power connection and not request vendor information. Used for legacy compatibility and debugging.
