I have an external 4 drive enclosure: AMS VENUS T4U (DS-2340U) which usbdevs shows as: addr 1: full speed, self powered, config 1, OHCI root hub(0x0000), (0x1166)(0x0000), rev 1.00 port 1 addr 2: full speed, power 2 mA, config 1, 4HDD(0x2106), NOVAC Co., Ltd.(0x09cc), rev 1.02 port 2 powered port 3 powered port 4 powered AMS tech supports says: Venus T4U is USB 2.0 based. High-Speed and Full Speed compatible modes. 6.2-PRERELEASE says: da1 at umass-sim0 bus 0 target 0 lun 0 da1: < Combine Mode 0102> Fixed Direct Access SCSI-2 device da1: 1.000MB/s transfers da1: 1144662MB (2344268304 512 byte sectors: 255H 63S/T 145923C) da2 at umass-sim0 bus 0 target 0 lun 1 da2: <SEAGATE ST3400620A -2 3.AA> Fixed Direct Access SCSI-2 device da2: 1.000MB/s transfers da2: 381554MB (781422768 512 byte sectors: 255H 63S/T 48641C) which is proper detection of the two configured devices but transfers are painfully slow. A quick search of the archives did not yield any ideas of how to proceed from here. Any possibility of getting higher speed out of this thing? /\/\ \/\/
