CONNECTING USB TYPE-C DEVICES
First Claim
1. A method comprising:
- sending, by a user equipment, a first predetermined test pattern to a first accessory including a first connector, when the first accessory is in a first mode of operation;
determining, by the user equipment, a configuration of the first accessory in the first mode by at least measuring a first time for the first predetermined test pattern to return from the first connector and a data loop at the first accessory;
sending, by the user equipment, a second predetermined test pattern via at least the first connector; and
determining, by the user equipment, a presence of a data loop extension, by at least measuring a second time for the second predetermined test pattern to return from the first connector and at least one of the data loop at the first accessory or the data loop extension.

8. An apparatus comprising:
-
at least one input shift register; at least one output shift register, wherein the at least one input shift register and the at least one output shift register are coupled to a first connector; and at least one switch configured to feed data from the at least one input shift register to the at least one output shift register when the at least one switch is in a first state, the at least one switch configured to feed data from the at least one input shift register to an extension output when the at least one switch is in a second state, wherein the at least one switch is controlled based on at least one bit at an extension control position at the at least one input shift register, the at least one output shift register, or a combination thereof. - View Dependent Claims (9, 10)
