The following are USB features which are not supported by the hardware integration of the current device:
Feature | Reason |
---|---|
Virtualization (SRIOV or xHCI-IOV or ARM SMMU) | No Support |
SuperSpeed (5 Gbps) Device Mode | No Support |
Debug Trace for USB | No Support |
Attach Detection Protocol (ADP) | This function is not possible because the USB2 PHY implements 3.3v ESD on the VBUS pin. |
5 volt compatible VBUS pin | This function is not possible because the USB2 PHY implements 3.3v ESD on the VBUS pin. Note: The VBUS signal should be applied to a 20k/10k voltage divider which divides the potential by 3. This allows the VBUS signal to go up to 10.75 volts before exceeding the VBUS pin maximum of 3.63 volts. |
NRDY Event TRB, when operating in host mode | NRDY Event TRB is not supported when operating in host mode. |
Halt Endpoint Command TRB, when operating in host mode | Halt Endpoint Command TRB is not supported when operating in host mode. |
OTG Protocol, for USB Type-C applications | OTG Protocol is not supported for USB Type-C applications. |
Light HC Reset Capability (LHRC) | No Support |
xHCI Debug Capability (Debug Port) | No Support |
xHCI Save and Restore Operations | No Support |
HIMD, when operating in host mode | No Support |
Latency Tolerance Messaging | Set Latency Tolerance Value Command is not supported |
Negotiate Bandwidth Command | No Support |
Number of slots limited to 64 | Total for USB2 and USB3 |
Number of active periodic endpoints limited to 96, when operating in host mode | No Support |
Smart ISO | Deprecated in USB 3.2 specification |
Secondary Streams | No Support |
PTM, when operating in device mode | No Support |
