This describes settings for the USB-driver of the Trizeps-module.
The Trizeps IV(M) has three USB-Ports:
If a cable is attached to the USB-Slave port, the USB-OTG port is automatically disabled. After deattach of the cable it gets reconnected.
The Trizeps V has three USB-Ports:
Unlike Trizeps4, where USB-Slave can't work at the same time as USB-OTG, all ports may run concurrently.
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\Usb20fn] |

---|---|---|
Key | Type | Description |
HighSpeed | DWORD | 0 Only use Full-Speed for USB-Slave port. Note that this does not work, if the module is attached to a USB-hub. 1 Use High-Speed. |
The Trizeps VI has two USB-Ports:
A mounting option exist to route the USB-OTG-pins to the USB-Slave-pins of Trizeps4&5. But this might impact the usable speed on the USB-bus and is not the default setting.
For a normal configured Trizeps6, you should set the OTG-Registry setting to one of following values:
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\HCD] ( first Host-Port) |
||
---|---|---|
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\OTG\HCD] ( OTG-Port, when configured as host) |
||
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\OTG\UsbFn] ( OTG-Port, when configured as slave) |
||
Key | Type | Description |
HighSpeed | DWORD | 0 Force port to only use Full-Speed. 1 Use High-Speed. |
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\Usbfn] (Trizeps4 & 5) |

---|---|---|
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\OTG] (Trizeps6) |

Key | Type | Description |
OTG | DWORD | 0x......FF OTGMode: 0x0 (default): OTG-Port is Host, or disabled if USB cable is plugged. 0x2: Switch mode depending on USB-Slave-Cable detect pin. cable plugged: Slave, cable not plugged: Host. 0x3: Switch mode depending on OTG-ID-Pin (Status is polled). 0x5: OTG-Port is Slave only. 0x6: Switch manually (set cable=1 !) more info: (*) follow link @end of table 0x....FF.. GPIO to switch external charge-pump (5V enable for OTG-port). Use 0x10 for GPIO_0. Use 0x00 to disable this feature. 0x...1.... Inverse polarity of external charge-pump-enable pin (5V). 0x...2.... Keep VBUS-powered (Trizeps6 only: VBUS-Input need 5V if OTGMode = 0x5. This bit only needs to be set if VBUS is not supplied by external pin!) 0x...4.... Ignore VBUS-Input. (Trizeps6 only; 15.04.2016) 0x...8.... Simplified OTG mechanism. (Trizeps6 only; 20.09.2016) |
cable | DWORD | Use USB Slave Cable-Detect-pin. (30.06.2009) 0 or missing use pin 55 of SODIMM200 as usb-cable-detect. 1 attempt to detect cable by host SOF-messages. 2 attempt to detect cable by VBUS Signal. (13.10.2009) |
