Attention is currently required from: laforge, tnt. Hello Jenkins Builder, tnt, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/osmo-e1-hardware/+/29948 to look at the new patch set (#2). Change subject: fw/e1-tracer: Additional USB configuration for "osmo-e1d compatible mode" ...................................................................... fw/e1-tracer: Additional USB configuration for "osmo-e1d compatible mode" This adds a second USB configuration to the e1-tracer firmware. This configuration is closer to the USB configuration of an icE1usb and hence paves the way for using osmo-e1d with the tracer. The main conceptual difference between the existing "legacy" configuration and this new "e1d compatible" configuration is to have two USB interfaces, one for each direction of the traced E1 interface. Each interface has its own separate two altsettings, one for the disabled and one for the enabled state. Unmodified osmo-e1d will not work straight away with this, as it expects ISO OUT and ISU Feedback endpoints, which a pure rx-only tracing device of course doesn't have.
