Summary: zd1211rw with new mac80211 does not work with Yakumo
QuickWLAN USB (ZyDAS)
Product: Drivers
Version: 2.5
KernelVersion: 2.6.25.2
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: high
Priority: P1
Component: network-wireless
AssignedTo: drivers_network-wireless at kernel-bugs.osdl.org
ReportedBy: gilles.mocellin at free.fr
Latest working kernel version:
2.6.24
Earliest failing kernel version:
2.6.25
Distribution:
Debian SID
Hardware Environment:
Yakumo QuickWLAN USB (ZyDAS)
Software Environment:
wpa_supplicant
Problem Description:
I use a USB wireless adapter : Yakumo uickWLAN USB 2.0, with a ZyDAS
chipset, zd1211.
I use it with a WPA AP, running with OpenWRT on a Lynksys wrt54GS.
It works with the kernels from 2.6.18 to 2.6.24.
It does not initialise, nor scan with 2.6.25.
I saw thiat this driver (zd1211rw) has changed to the more generic
mac80211 layer from Deviscape.
The symptome is : the link LED stays off, wpa_supplicant cannot initiate
scan, and there is no network connection.
