Well, I just tried this driver on the TBS6985. The adapters are correctly detected and attach. I can tune to a channel with szap-s2, but after configuring them in TvHeadend:
Jan 18 14:38:50 satellite tvheadend[1263]: subscription: 'initscan' subscribing to mux, weight: 2, adapter: 'Tmax TAS2101 : DVB-S #2', network: 'Sky', mux: '11798H'
Jan 18 14:38:50 satellite tvheadend[1263]: mpegts: 11390H - initial scan no data, failed
Jan 18 14:38:50 satellite tvheadend[1263]: subscription: "initscan" unsubscribing
Jan 18 14:38:50 satellite tvheadend[1263]: mpegts: 11565V - starting for 'initscan' (weight 2)
Jan 18 14:38:50 satellite tvheadend[1263]: mpegts: 11565V - tuning on Tmax TAS2101 : DVB-S #1
Jan 18 14:38:50 satellite tvheadend[1263]: subscription: 'initscan' subscribing to mux, weight: 2, adapter: 'Tmax TAS2101 : DVB-S #1', network: 'Sky', mux: '11565V'

Jan 18 14:38:50 satellite tvheadend[1263]: mpegts: 12629V - tuning on Tmax TAS2101 : DVB-S #0
Jan 18 14:38:50 satellite tvheadend[1263]: subscription: 'initscan' subscribing to mux, weight: 2, adapter: 'Tmax TAS2101 : DVB-S #0', network: 'Sky', mux: '12629V'
Similarly, tuning and setting up the dvr0 device via szap-s2, yields no output when using mplayer, or simply cat /dev/dvb/adapter4/dvr0 >out.ts
dvbtraffic shows this when tuned to BBC 1 NI HD:
