Hi,

thanks for the answers.

I soldered them like you said, 1 to 1 and so on... Still the same behavior:

dmesg -c

[26970.367187] EAC mode: play disabled, rec disabled
[26994.984375] musb_stage0_irq 570: VBUS_ERROR in a_wait_bcon (90, <VBusValid), retry #3, port1 00080108
[26994.984375] tusb_source_power 629: VBUS a_wait_vfall, devctl 90 otg 154 conf c0000001 prcm 00a80500
[26995.046875] tusb_source_power 629: VBUS a_idle, devctl 80 otg 184 conf c0000001 prcm 00a80500
[26995.054687] tusb_source_power 629: VBUS a_idle, devctl 80 otg 184 conf c0000001 prcm 00a80500
[27012.031250] EAC mode: play enabled, rec enabled

Connecting 4 to 5 is not necessary, because I enable the hostmode manually.
