Similar to #1272 and #1273.

The hp-3457a driver sends "END ALWAYS" before identifying a device. This annoys the Rigol DP821A, and will quite likely bother other devices too. SCPI drivers shouldn't send specific commands before identifying a device.

The old-style "ID?" query also makes it unhappy; that aspect is as per #1273.
