Subject: uni-t-dmm: Require conn parameter for scan
X-Git-Tag: libsigrok-0.2.2~94
X-Git-Url: https://sigrok.org/gitaction?a=commitdiff_plain;h=56e76981bc5e8e8d138275ad215e96d8ab4939af;p=libsigrok.git

uni-t-dmm: Require conn parameter for scan

Since the uni-t-ut32x series handles devices with the same USB VID.PID,
which is linked to the WCH CH9325 USB/HID-UART interface chip, this
driver can no longer assume it can handle anything with this VID.PID.
