rt73usb doesn't work at bootup have to re-insert

[fadlouni]

Hi.

i have this Linksys WUSB54GC 802.11g wireless usb adapter. i'm on gentoo running 2.6.30-gentoo-r4 amd64. this adapter uses the rt73usb module (with it's submodule dependencies). at bootup, the hardware is recognized fine, the kernel modules are autoinserted. dmesg shows things are fine:
Registered led device: rt73usb-phy0::radio
Registered led device: rt73usb-phy0::assoc
Registered led device: rt73usb-phy0::quality
usbcore: registered new interface driver rt73usb
ACPI: PCI Interrupt Link [APC5] enabled at IRQ 16
HDA Intel 0000:02:00.1: PCI INT B -> Link[APC5] -> GSI 16 (level, low) -> IRQ 16
HDA Intel 0000:02:00.1: setting latency timer to 64
EXT3 FS on sda3, internal journal

forcedeth 0000:00:07.0: irq 25 for MSI/MSI-X
rt73usb 1-4:1.0: firmware: requesting rt73.bin


/var/log/messages shows the same.

but it doesn't work, and wpa_client never connects, wpa_cli doesn't show anything, wlan0 interface shows up but no ip address.

However if i just remove the linksys usb adapter and reinsert it, then everything works perfectly, and wpa_client connects and i get an ip address and i can go to the internet.

note upon removing the usb adapter i get the following in dmesg:
and at the end of dmesg i have these:
usb 1-4: USB disconnect, address 5

phy0 -> rt2x00usb_vendor_request: Error - Vendor Request 0x0a failed for offset 0x0000 with error -19.


then afterwards i re-insert the adapter and things work perfectly as already explained.

as i'm not a kernel expert, anyone can give me a hint how to fix this so at reboot it connects on it's own?
