| 59 | Those are information on the vendor and kind of the device. |
| 60 | The vendor ID is the actual vendor of the device. |
| 61 | The device type is the basic type of the device: |
| 62 | ||= Type =||= Symbolic name =||= Description =|| |
| 63 | ||0 ||GENERIC ||This is a generic device. It only supports this Bank. || |
| 64 | ||1 ||BRIDGE ||This device interacts as bridge between at least two different physical or logical ports. || |
| 65 | ||2-63 || ||Reserved. || |
| 66 | ||64-127 ||VENDOR00 - VENDOR63 ||Vendor specific type. Depends on the Device Vendor. || |
| 67 | |
| 68 | The subtype defines the device more closely. The subtype fully depends on the type. However the value of zero should be used for the most basic kind of this type of device. |
| 69 | |
| 70 | For devices of type GENERIC the subtype MUST be zero. |
| 71 | For devices of type BRIDGE the following subtypes are defined: |
| 72 | ||= Type =||= Symbolic name =||= Description =|| |
| 73 | ||0 ||GENERIC ||Generic bridge device. || |
