Hi,
I have some problems with the new driver of hp8200. First it seems that it
is recognized as a disk and not as a cd writer:
Jul 5 21:47:06 uwlx003 kernel: Vendor: HP Model: CD-Writer+
8200e Rev: 0001
Jul 5 21:47:06 uwlx003 kernel: Type: Direct-Access
ANSI SCSI revision: 00
Jul 5 21:47:06 uwlx003 kernel: usb-storage: device scan complete
Jul 5 21:47:06 uwlx003 kernel: Attached scsi removable disk sda at
scsi1, channel 0, id 0, lun 0
Jul 5 21:47:06 uwlx003 scsi.agent[2491]: sd_mod: loaded
sucessfully (for disk)
After looking at the debug messages, I was able to hack around this
with this brute force patch:
--- shuttle_usbat.c.orig 2005-07-11 09:01:52.000000000 +0200
+++ shuttle_usbat.c 2005-07-11 09:01:57.000000000 +0200
@@ -859,7 +859,7 @@
US_DEBUGP("usbat_identify_device: Cylinder low is %02X\n", status);
- if (status == 0x14) {
+ if (status == 0x14 || status == 0x80) {
// Device is HP 8200
US_DEBUGP("usbat_identify_device: Detected HP8200 CDRW\n");
info->devicetype = USBAT_DEV_HP8200;
After this I was able to mount a CDROM. However when I tried to blank a
cdrw using
cdrecord blank=all dev=0,0,0
I got an oops. Any idea?
Thanks, Laszlo
