Trizeps USB-Driver
This describes settings for the USB-driver of the Trizeps-module.
Trizeps 4
The Trizeps IV(M) has three USB-Ports:
- USB-Host
- USB-OTG
- USB-Slave
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.
Trizeps 5
The Trizeps V has three USB-Ports:
- USB-Host
- USB-OTG
- USB-Slave (HighSpeed)
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.
|
Trizeps 6
The Trizeps VI has two USB-Ports:
- USB-Host (HighSpeed)
- USB-OTG (HighSpeed)
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:
- 0: if USB-OTG should only work as Host ( Also set DynamicClientLoad = 0).
- 3: if you attached a OTG-connecter (with ID and VBUS pins).
- 5: if you attached a OTG or USB-Slave connector and the port should work as Slave only.
- 0x20005: if you want to operate the USB-Port as USB-Slave, but left VBUS floating. (This setting is usefull if you want to debug an application through ActiveSync, but can only connect to a USB-A connector).

| 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) |
