Because:

1) it clashes with USB device side mode, where the config index is received 
from Host

2) Different device drivers might want different configurations.

3) The driver for the active configuration might not be loaded.

This is interesting:

The device says it only has one configuration! So setting index 1 should not 
be allowed.

Could you try to change the check in the ubsa2.c probe routine to check for 
config index 0 instead?

Mostly config index 0 is used in USB devices.

%cat *[ch] | grep -i "config.*Index"
#define U3G_CONFIG_INDEX        0
        if (uaa->info.bConfigIndex != U3G_CONFIG_INDEX) {
#define UARK_CONFIG_INDEX       0
        if (uaa->info.bConfigIndex != 0) {
#define UBSA_CONFIG_INDEX       1
        if (uaa->info.bConfigIndex != UBSA_CONFIG_INDEX) {
#define UCHCOM_CONFIG_INDEX     0
        if (uaa->info.bConfigIndex != UCHCOM_CONFIG_INDEX) {
        if (uaa->info.bConfigIndex != 0) {
#define UFTDI_CONFIG_INDEX      0
        if (uaa->info.bConfigIndex != UFTDI_CONFIG_INDEX) {
#define UGENSA_CONFIG_INDEX     0
        if (uaa->info.bConfigIndex != UGENSA_CONFIG_INDEX) {
#define UIPAQ_CONFIG_INDEX      0       /* config number 1 */
        if (uaa->info.bConfigIndex != UIPAQ_CONFIG_INDEX) {
            "config number: %d\n", alt_index);
#define UMCT_CONFIG_INDEX       1
        if (uaa->info.bConfigIndex != UMCT_CONFIG_INDEX) {
#define UMOSCOM_CONFIG_INDEX    0
        if (uaa->info.bConfigIndex != UMOSCOM_CONFIG_INDEX) {
#define UPLCOM_CONFIG_INDEX             0
        if (uaa->info.bConfigIndex != UPLCOM_CONFIG_INDEX) {
#define UVISOR_CONFIG_INDEX     0
        if (uaa->info.bConfigIndex != UVISOR_CONFIG_INDEX) {
#define UVSCOM_CONFIG_INDEX     0
        if (uaa->info.bConfigIndex != UVSCOM_CONFIG_INDEX) {

Try changing "UBSA_CONFIG_INDEX" to zero.

If it works I will commit a patch for this.

When you cannot retrive the strings, I think your device is gone! (Crashed)
