The ASPEED USB 2.0 Virtual Hub Controller implements 1 set of USB Hub
|
||
|
|
register and several sets of Device and Endpoint registers to support
|
||
|
|
the Virtual Hub's downstream USB devices.
|
||
|
|
|
||
|
|
Supported number of devices and endpoints vary depending on hardware
|
||
|
|
revisions. AST2400 and AST2500 Virtual Hub supports 5 downstream devices
|
||
|
|
and 15 generic endpoints, while AST2600 Virtual Hub supports 7 downstream
|
||
|
|
devices and 21 generic endpoints.
