Abstract
Abstract An enhanced Universal Serial Bus (USB) interface provides for the communication of standard USB signalling and non-standard USB signalling, which may be alternate voltage signals. The chassis within data processing devices operable for receiving such an enhanced USB connector into an enclosed enhanced USB receptacle provide a keying configuration so that the standard USB connector portion is not matable with the non-standard USB portion.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
130 words
A data processing system, comprising: a hub including a processor, said hub further comprising: an enhanced universal serial bus ("USB") receptacle operable for providing (1) standard USB signalling via a standard USB receptacle, and (2) non-standard USB signalling via a non-standard USB receptacle; a node device coupled to said hub by an enhanced USB connection carrying said standard and non-standard signalling, wherein said enhanced USB connection having a plug connector which comprises: a standard USB portion operable for carrying said standard USB signalling; and a non-standard USB portion operable for carrying said non-standard USB signalling; and a chassis enclosing said hub and said enhanced USB receptacle, wherein said chassis includes a keyed hole for preventing said standard USB portion of said plug connector from mating with said non-standard USB receptacle.
Claim 2
Dependent Claim
130 words
A data processing system, comprising: a hub including a processor, said hub further comprising: an enhanced universal serial bus ("USB") receptacle operable for providing (1) standard USB signalling via a standard USB receptacle, and (2) non-standard USB signalling via a non-standard USB receptacle; a node device coupled to said hub by an enhanced USB connection carrying said standard and non-standard signalling, wherein said enhanced USB connection having a plug connector which comprises: a standard USB portion operable for carrying said standard USB signalling; and a non-standard USB portion operable for carrying said non-standard USB signalling; and a chassis enclosing said hub and said enhanced USB receptacle, wherein said chassis includes a keyed hole for preventing said standard USB portion of said plug connector from mating with said non-standard USB receptacle.
Claim 3
Dependent Claim
27 words
The data processing system as recited in claim 1, wherein said keyed hole permits a polarized coupling of said non-standard USB portion with said non-standard USB receptacle.
Claim 4
Dependent Claim
26 words
The data processing system as recited in claim 1, wherein said keyed hole permits a coupling of said non-standard USB portion with said non-standard USB receptacle.
Claim 5
Dependent Claim
21 words
The data processing system as recited in claim 3, wherein said non-standard USB portion has a cut-out in its connector housing.
Claim 6
Dependent Claim
33 words
The data processing system as recited in claim 1, wherein said enhanced USB receptacle is operable for providing said standard USB signalling that includes a differential data signal and a 5 volt signal.
Claim 7
Dependent Claim
28 words
The data processing system as recited in claim 5, wherein said enhanced USB receptacle is operable for providing said non-standard USB signalling that includes a non-5 volt signal.
