Message-ID: <20020126133708.A94104@iguana.icir.org> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline User-Agent: Mutt/1.3.23i Sender: owner-freebsd-hackers@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG Hi, I just got a simple compactflash/smartmedia reader, which i was trying to use on by 4.5-RC2 system. When i plug in the thing, i get the following: Jan 26 22:02:13 luigi /kernel: umass0: USB ReaderSSFDC-CF 0.74 USB ReaderSSFDC-CF 0.74 , rev 1.10/0.74, addr 2 Jan 26 22:02:13 luigi /kernel: umass0: BBB reset failed, IOERROR Jan 26 22:02:13 luigi /kernel: umass0: BBB bulk-in clear stall failed, IOERROR Jan 26 22:02:13 luigi /kernel: umass0: BBB bulk-out clear stall failed, IOERROR Jan 26 22:02:13 luigi /kernel: (da0:umass-sim0:0:0:0): got CAM status 0x4 Jan 26 22:02:13 luigi /kernel: (da0:umass-sim0:0:0:0): fatal error, failed to attach to device Jan 26 22:02:13 luigi /kernel: (da0:umass-sim0:0:0:0): lost device Jan 26 22:02:13 luigi /kernel: (da0:umass-sim0:0:0:0): removing device entry The error messages are repeated typically 11 times if i unplug/replug the unit, except if i do it very quickly. The presence or absence of CF media does not seem to make a difference. How would i go about debugging the problem and trying to support this unit ? The maker is Transcend (www.transcendusa.com) but other than that I know very little about it... thanks luigi ----------------------------------+----------------------------------------- Luigi RIZZO, luigi@iet.unipi.it .
