I'm trying to get a Plantronics DSP-500 usb headset to work with linux. My system is running RedHat 9. When I plug in the device, the system correctly loads the audio.o module. But when I try to write to /dev/dsp, I get a divide by zero error in the kernel module. This happens with Redhat's 2.4.20-19.9 (smp) kernel, a Redhat 7.3 kernel (2.4.18-?), as well as a vanilla 2.4.21 kernel. I'm trying 2.4.22-rc2 now. FWIW, this headset works fine in Windows, and various usb storage devices work fine with this computer, so I know it's not a hardware problem.
Here's the kernel error: Aug 13 03:49:05 dhcp-126-191 kernel: divide error: 0000 Aug 13 03:49:05 dhcp-126-191 kernel: audio soundcore agpgart nvidia parport_pc lp parport nfs lockd sunrpc autofs orinoco_cs orinoco hermes ds yenta_socket pcmcia_core 3c59x ipt_REJECT iptable_fi Aug 13 03:49:05 dhcp-126-191 kernel: CPU: 0 Aug 13 03:49:05 dhcp-126-191 kernel: EIP: 0060:[<f9c5c010>] Tainted: P Aug 13 03:49:05 dhcp-126-191 kernel: EFLAGS: 00010246 Aug 13 03:49:05 dhcp-126-191 kernel: Aug 13 03:49:05 dhcp-126-191 kernel: EIP is at drain_out [audio] 0x120 (2.4.20-19.9) Aug 13 03:49:05 dhcp-126-191 kernel: eax: 000004b0 ebx: 00000000 ecx: 00000000 edx: 00000000 Aug 13 03:49:05 dhcp-126-191 kernel: esi: 000004b0 edi: 00000001 ebp: f53a2000 esp: f53a3f18 Aug 13 03:49:05 dhcp-126-191 kernel: ds: 0068 es: 0068 ss: 0068 Aug 13 03:49:05 dhcp-126-191 kernel: Process bash (pid: 10695, stackpage=f53a3000) Aug 13 03:49:05 dhcp-126-191 kernel: Stack: f7817000 f7817710 00000000 f53a2000 00000000 00000000 00000000 f53a2000 Aug 13 03:49:05 dhcp-126-191 login(pam_unix)[2904]: session closed for user rootAug 13 03:49:05 dhcp-126-191 kernel: f7817710 f7817710 f7817000 f6935e00 f68edc00 f1544140 f9c5d8c4 f7817000 Aug 13 03:49:05 dhcp-126-191 kernel: 00000000 00000000 f68edc00 c36af340 f79f4180 f79f1700 c01483d2 f79f4180 Aug 13 03:49:05 dhcp-126-191 kernel: Call Trace: [<f9c5d8c4>] usb_audio_release [audio] 0x154 (0xf53a3f50)) Aug 13 03:49:05 dhcp-126-191 kernel: [<c01483d2>] fput [kernel] 0x102 (0xf53a3f70)) Aug 13 03:49:05 dhcp-126-191 kernel: [<c01469ad>] filp_close [kernel] 0x4d (0xf53a3f8c)) Aug 13 03:49:05 dhcp-126-191 kernel: [<c01564ca>] sys_dup2 [kernel] 0xaa (0xf53a3fa4)) Aug 13 03:49:05 dhcp-126-191 kernel: [<c010953f>] system_call [kernel] 0x33 (0xf53a3fc0)) Aug 13 03:49:05 dhcp-126-191 kernel: Aug 13 03:49:05 dhcp-126-191 kernel: Aug 13 03:49:05 dhcp-126-191 kernel: Code: f7 f3 40 e8 b8 9d 4c c6 85 c0 0f 85 69 ff ff ff c7 04 24 4c --Mike ------------------------------------------------------- This SF.Net email sponsored by: Free pre-built ASP.NET sites including Data Reports, E-commerce, Portals, and Forums are available now.
